Hardware :: Choppy Sound When Play Through ALSA
Mar 1, 2011
I have an old Aureal Vortex 2 (by Diamond Multimedia) installed in my system (C2Q @3.4GHz, P35 motherboard), along with the on-board audio. I'm using my PCI sound card with my headphones and running everything else off of the onboard audio. Since it seems to have better sound, I would use it a lot more, but it skips like crazy whenever I try to play sound through ALSA. It sounds like something is sporadically dropping audio frames. The onboard audio works fine with ALSA.
I'm running Kubuntu 10.10 (2.6.35-25, gcc 4.4.5). I think it worked fine with earlier software, but I can't remember for sure. I've tried mplayer and kaffeine (xine backend). When using mplayer, the experimental openal works perfectly, but the advanced options for kaffeine are pitiful. I'm looking at switching video players (probably xbmc or a frontend for mplayer), but I assume I won't be able to completely avoid ALSA. I've done a quick search on google, but if there was anything useful, it was choked out by decade old discussions on getting the card to work at all.

I have Ubuntu Lucid. If i dont' mistake, it should be possible to hear several applications playing sound simultaneously, with ALSA. But if 1 app is already playing, then starting a second one give always "device is busy".

I've been having some issues with my sound card since I cannot play a sound with my current user. As a root user I can play sounds with "aplay" but as my regular user, I can't play anything

how can I play audio (Mythtv - Play Music) simultaneously on two sound cards using ALSA drivers. I have two cards working well. One card is an onboard Intel cards, and the other card is a USB Audio card. Both cards are working well. I use the onboard Intel to output SPDIF to an amplified. The second USB card is bound to MPD service and it outputs an analog signal to a second amplified. I'd like to have the following configuration: Play to the default card with 5.1 passthrough, while the second card, connected to a second amplifier, plays an analog signal to the same audio played by Mythtv Play Music. In other words, I need to mix somehow and play the same audio on both cards.
Here is the list of cards:
root@mythtv:~# aplay -L
null
Discard all samples (playback) or generate zero samples (capture)

I'm having trouble getting ALSA to play multiple sound streams (multiple sounds at once). My code is running on an embedded ARM board using a AC97 sound. It will only play one without any mixing, I have to use pure ALSA as higher sound mixers are a nightmare to cross compile for ARM. I've tested my system with aplay for example
aplay -D plughw:0,1 bang.wav
works fine. So I tried dmix with
aplay -D plug:dmix Win.wav
That gave the following error
ALSA lib pcm_direct.c:1587snd_pcm_direct_parse_open_conf) The field ipc_gid must be a valid group (create group audio)
aplay: main:550: audio open error: Invalid argument
I checked asound with
/etc # cat asound.conf
pcm.EP93XX {
type hw
[code]....
Does this mean dmix will not work? Is there someway with the above setup I can play multiple sounds? I have to use the vendor ALSA build (so can't update ALSA), I can change the .confs however. Also because I'm cross compiling things like pulseaudio SDL are very difficult to get working, so I basically need to use the above ALSA. Is there anyway I can find if dmix exists on the system?
Should add aplay -L does show dmix ?
iec958 'cards.pcm.iec958'
spdif 'cards.pcm.iec958'

Im trying to play some videos with vlc but they are too choppy, I guess my comp is too slow. They are something like 1700x1000 h.264. What can I re-encode these too to maintain good quality but increase playback speed? If possible, an ffmpeg command to do this would be awesome.

My last laptop was replaced (I gave it to my step-dad, his laptop broke and I bought myself a new one).
I am running Squeeze (as I was on my other laptop) and everything is fine except for the games. On my other laptop games like OpenArena and Warzone 2100 ran perfectly fine, but on this laptop, they are impossible to play. The game will open, but everything is so slow and choppy that it takes a couple of minutes to even move the cursor to the exit game buttons.
My current laptop is an HP ProBook4525s with the current specs:
AMD Athlon Dual-Core P340 2.2 GHz processor
2GB DDR3 RAM
ATI Mobility Radeon HD 4250 Graphics Card
I'm not sure what other information to put here, I've tried searching how to fix this and most people say to lower the resolution and details for the games but that doesn't work, heck, even Tux Kart is too slow to play!
When I installed squeeze I was informed that I didn't have the rtl8168d-2.fw firmware for my laptop, I'm not sure if that helps here at all (can't seem to find what it is for, the only things that google gives me are very technical with fixes that involve re-compiling the kernel).

I'm having issues playing HD videos ( some with 720p level, much more apparent with 1080p level one) The video appears to slow then becomes choppy, becoming de synced from the audio that carries on as normal. This occurs with both VLC player and XBMC, though the latter is better. My specs: Fedora 12 3.2 Ghz P4 processor 1Gig ram Radeon 9800 xt gfx card (I couldn't get the 9.3 ati driver to work)

I'm trying to figure out what in the world is going on with my sound in OpenSuSE. I put in a brand new Audigy chipset soundcard and finally got some sound to come out of the speakers. I used the guide here: SDB:AudioTroubleshooting - openSUSE. to fix the permissions on my sound and am able to get sound-test to play sounds as well as connect to the sound device in my vmware and play sounds. That being said, I have terrible sound quality coming out. There is a lot of static sound like white noise and the volume of the actual sound played is very low compared to the noise. The sounds also distort somewhat.
I have tried the pulse audio change in the tutorial above also and have been searching around google. The only problem that I saw similar was a person who fixed the problem by updating KDE. I don't have KDE, I'm using Afterstep.

I have installed xubuntu version 10. My sound card is a Yamaha dS-1S, and seems to be properly configured. Alsa mixer doesn't indicates any error. However, I can't manage to get any sound. I have checked that jacks are correctly plugged.

I'm running Kubuntu 9.10 X64, and am using ALSA for my sound. I have no trouble with sound: VLC, Adobe's Flash plugin, Java, etc. all work properly. When I run the Gnash standalone player, sound does not work at all.
When I run Gnash in a terminal, I get this:

I wanted to hear some music from my audio library, so I turned on banshee, all the sudden the audio started to hear choppy, no unusual disk activity, no slowness of my laptop. I restarted the laptop since, I had a big Red buton that asked for it. After reboot tried listening to my music and the same result choppy audio. Tried rebooting again, same thing. Has anyone experienced this issue with audio after todays update? My laptop is a Lenovo Thinkpad t61 2 GB RAM and fedora 11 x_64

I can hear everyone clearly but when I go to talk, my voice comes out choppy. However, when I use Sound Recorder to record myself, everything plays back clearly.

i'm having choppy sound in 10.04. i didn't have it in 9.10 and i don't know enough about how it works to try to fix it.
here are some things i have noticed, however.
1. the choppy sound is present in a 64bit and 32bit install. at first i thought it may just be a 64bit issue so i reinstalled to 32bit and it is still present.
2. it does not seem to matter what media type i am playing. i notice it most with videos from videos and music from pandora.
3. it seems to occur more often at intense moments of music. i'm not really sure how to describe it, but it is typically the climax of a song where it is a little louder and more intense.

When I am scrolling using my touchpad on my Dell E1505 regardless of which program, my sound skips. Its like it becomes scratchy or similar. I had the same problem with 10.04 and fixed it by modifying some modset file. Said it had something to do with my ATI X1400 GFX card too.

Since I upgraded to 10.04 (from 9.10) I've been running into trouble with my wireless headset. Ever since the upgrade, I've had issues with the audio being very choppy (it sounds kind of like static) through the headset while listening to anything from an mp3 to a ..... video.
The two things I've noticed about it are that it is ONLY when using the headset, and the audio is fine running through the built in speakers. The other thing is that it only seems to happen when there is something going on on screen (for example, with a ..... video, scrolling up and down a page makes it much worse, as does having the video embedded in another page, while minimizing the page eliminates problem; or while listening to music, while the visualizer is running, it has problems, but when I get rid of it, it's fine.)
I have a somewhat old Dell Inspiron 6400 with 2 GB ram and 2 Intel core 2 T7400s, each at 2.16 GHz if that helps. I'm not sure how to check what sound card I have (still fairly new to linux).

After installing an external sound card, Im having some weird issues. The cards chipset is fully supported by suse, (CM8738) so I dont think thats the problem. Besides, I'm getting sound, but not in some applications. The system's sounds work just fine (login, logout themes) amarok plays without any problems, kaffeine, mplayer they all work flawlessly, in fact I can see the difference in quality between the onboard sound and my new card. However, no web browser is able to play any sound at all, firefox, opera or chrome, nothing,zip. Plus, vlc cant reproduce sound either, nor can smplayer.
I've tried switching channels on and off(muting)in kmixer and in alsamixer, on the console, with no results. I disabled the onboard audio on the bios before installing the new card, however my ati video card has integrated sound, which I cant disable.... I used to get this exact same problem randomly with the onboard sound, but I just had to go to kmixer and turn up the "pcm" channel volume, which was set to 0, and I had sound again on my browser. However this card's pcm channel is at max and turning it up or down affects the whole systems volume, not just the browser's. Is it better to just reinstall the sound system, if so how could I do that.

I am experiencing sound problems after an upgrade to kernel 2.6.29.6-213.fc11.i686.PAE from kernel 2.6.29.5-191.fc11.i686.PAE in several games like Neverwinter Nights (linux binaries) and Warcraft III (PlayOnLinux). The sound stops and changes into a very choppy annoying sound. When I boot into the old kernel the problems are gone.

My sound was working fine except I couldn't get system sounds (notifications) to work. So I decided to install pulseaudio to see if it would fix it. Now I get system sounds and my other sounds, but now in most things (such as firefox and warcraft 3) the sound is choppy. I've tried SDB:AudioTroubleshooting - openSUSE and a couple other things I've googled but it's not working for me. I'd like to be able to fix it or at least go back to the way it was.

In Gnome and XFCE I always have a choppy music playback. The music is never played smoothly. There is always hesitations in the playback, as if the CPU is running on 100% and cannot cope with the system load.
One of the reasons for that is (in my case) Pulseaudio.
Another reason is Gstreamer. When I choose Gstreamer as backend in KDE, I get the same choppy musicplayback as in Gnome or XFCE. With Xine as backend in KDE, everything is fine. So my conclusion is: with Xine, the sound would be fine in Gnome too.
So, I wonder if it is possible to use Xine as backend in Gnome too. Does anyone have experience with running Xine in Gnome and/or XFCE? What do I need to do to set Gnome/XFCE, so that it uses Xine instead of Gstreamer?
Or is there maybe a special setting, I have to apply? In gstreamer-properties I have tried all possible settings, but this didn´t change anything to the quality of sound.
My experience is also: this choppy sound is hardware-independend. It doesn´t matter which hardware I use, the sound is choppy. It is also distro-independend. The sound is choppy in openSUSE (gnome and in KDE with applied Gstreamer backend), in Ubuntu, Xubuntu, Fedora with Gnome, Linux Mint with Gnome.

I run ubuntu 10.10 with an 870-g45 motherboard which contains a VIA VT1828S integrated sound chip with 8 audio channels as it states on [URL]... I am having issues with getting microphones to work properly on my computer. Sound output works great but microphones don't. I've noticed when I tested mic's on the sound configuration it would act like it gets input but it would be choppy or laggy sound. Anytime i talk to people on voice chat they say my voice sounds like it keeps clipping in and out and they can't understand a thing I say. I have tried looking on google but any fix I looked at didn't seem to work for me. I don't know if it's motherboard related

to start off, i'll post the specs of the machine:
dell inspiron e1505
3.2 gb ram
1.86 ghz intel core duo
ati x1400 gfx
opensuse 11.4 kde 32 bit.
okay, here are the details: can't play any audio with amarok when desktop effects are enabled because the minute a window is moved, it will distort the audio. even when disabling desktop effects, some applications still cause this. can't play videos videos even with desktop effects disabled because of the same reason.
i just switched from ubuntu and when i ran version 11.04, i had to disable kms to do anything. i tried on opensuse 11.4 and the audio was flawless but the gfx went all to hell.

basically, sound will cut in and out. if i'm on videos, whenever sound cuts out, the video will continue for exactly two seconds and stop. sometimes i can reload the videos video, and it'll either play for two seconds without sound, or go normal, but usually for only a little time, not even a minute. similar problems for amarok, spotify and other applications using the sound card. this is the output when trying to restart the alsa demon
code:

i've tried reconfiguring alsa by using the alsaconf application, which didn't help. the output from restarting the alsa demon, may indicate that the correct driver isn't loaded.

I am having problems getting sound to work. I have pasted my output from AlsaInfo.sh in hopes that someone can assist me. I have been able to fix this with the AlsaCompile scripts for Ubuntu. I am wondering if this is a distro related issue. If not I will gladly send to the alsa project.

I am using linux mint 9 with kernel 2.6.32.29. I upgraded from alsa 1.0.23 to 1.0.24 using the alsa upgrade script. Sound was working just fine before on my Asus Xonar DS, However, my nvidia geforce 430's hdmi audio card is not recognized in 1.0.23 but it is in 1.0.24. Though the card is detected, I have no sound on either cards now.

when i plug in my headphones i was getting sound output both from the laptop speakers and the headphones, then i tried changing the sound.conf file and still no success and then i tried reinstalling the alsa - i downloaded the latest alsa-driver and alsa-lib and installed them, but when i rebooted there was no more sound from the headphones when i plug them in. I don't know what to do, i tried reinstalling alsa multiple times but still no success. Is there any way to bring back my previous configuration when i installed slackware ? Or some way to roll back using the installation dvd ?

I am using a couple of Debian Distro (Sid and Lenny) add some Ubuntu into the mix. I made the switch because I was amazed and satisfied with Debian --> once installed, everything works. For me that's okay for o so many years now. I don't question a lot because it just works and I do my job on it satisfactorily. Namely programming the LAMP style programming. Lately I have been using Debian to communicate over the internet -- using Skype and Pidgin and other such things, not to mention listening to music, watching movies, just using the default applications when I originally install Debian.
Along the way, I need to configure something -- that is desktop related -- like the screen resolution of a new LCD monitor replacing the old one and such. Now about my sound -- I'm not touching it because it is working. But that is not the case always. Now I have a constant error -- it is irritating. Rhythmbox don't make a sound always when I have open a web browser (iceweasel, chrome, epiphany) and a site with multimedia object on it -- like a video or something. So how do I correct this? How do I know, too what I am using -- ALSA or Pulseaudio?

So I've got a new system on which I had to re-install Debian, and I've been trying to fix the sound today, but it doesn't seem to work... I've kept the same ALSA configuration (except a minor adjustment to the card number as this system appears to have two cards instead of one), but it doesn't seem to work as expected. I got this weird error while running an app that uses ALSA:
Code: Select allALSA sound driver initializing...
ALSA lib pcm_dmix.c:1024:(snd_pcm_dmix_open) unable to open slave
  --> (Device: default)...Failed: Operation not permitted
In VLC it works fine, provided that I manually choose the right device under Audio -> Audio Device.here's my /etc/asound.conf:
Code: Select alldefaults.ctl.card 1
pcm.dsp {
  type plug
  slave.pcm "dmix"
