Ubuntu Multimedia :: Audio [Swapped Channels - Crappy Sound]
Dec 8, 2010
I have recently installed Ubuntu 10.10 and it got really nice interface and is pretty user friendly, but I got an issue directed to sound. I have used Ubuntu 9 last time and had the same problems. So here are my problems: I got Realtek AC'97 ALC655 on-board sound card with 5.1 support and hardware mixing. By reading posts on google and this forums I got an idea it should work OOB but it won't.
The issues: *when I set the sound output to 5.1 + 1 stereo input it makes all the speakers work but act in weirdo way and testing the each speaker confuses me even more, because it's like(test=real sound source):
rearleft=subwoofer
rearright=center
center=frontleft
frontleft=rearright
frontright=rearleft
subwoofer=frontright. o.O
*the sound quality is crappy, it feels like it is old radio player because it requires some seconds for sound to 'condensate' and play normally with some crackles and other distortions.. And I'd like to also ask what sound system is mainly used in Ubuntu? Is it alsa,pulse or OSS? Since I can't find a way to see it.

every time i watch a video at ....., or use audacious to listen to music (or instead use grooveshark) the sound jumps forward automatically for some strange reason.
The other problem is the graphics. Everytime i enter a website i see the graphics but pixelated. At 100%. Well. i don't see all images or banners like this, just a few. (i.e:Google logo, flickr logo).
im using a laptop. Acer 5735Z. Mobile Intel Graphics Media Acelerator 4500MM

I have noticed a few threads on getting sound to work properly. I had a problem getting my internal sound card to work on 5.1 channels and investigated the links and information given in the various threads and found that there are slight differences from the references to what I had to do. Firstly, it's a good idea to read through these links first.

I use Kaffeine Version 1.0-pre2 and xine 0.99.6 on Fedora 12 64-bit. If I try to watch HD-channels (such as Das Erste HD, ZDF HD, arte HD), there is no sound (or just a few seconds). I read some times, that setting the audio buffer to 750 and the video buffer to 1000 should solve the problem

first of all im new to OpenSuse i have been using different distros since early 90's if theres one i havent tried i would be very surprised anyway im very picky when it comes to sound and picture maybe its the fact that im a developer and also art director anyhoo i got tired of my HTPC ( windows ) i thought linux has to be able to do it just as well i mean i only use it for movies and music but was surprised to see how video works in linux picture is somewhat ok compared to Windows but movement is another story even vsync off it looks like a old VHS tape when it should be DVD. Cam-panning is even worse. How is this and can it be fixed?

I've installed RPMforge and Smart Package Manager.
I had to create my own Centos 5.5 channels to sync yum repos and smart channels.
Here's the Centos 5.5 channel file for Smart:
Just shut Smart PM down, copy this file into /etc/smart/channels, and restart smart.
Smart should then detect the new channels (repos) for Centos 5.5
Update your channels in Smart, and you should then have yum repos and smart channels both in sync, looking at the same set of packages.
Copy this to CentOS-Base.channel, and add it to the /etc/smart/channels directory.
# CentOS-Base.repo

# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and

Only my 'front' sound output is working. No 'rear', 'side', or 'center'. And alsamixer only shows 'Master' 'PCM' & 'Capture' It's the onboard sound on a Asus M4A89TD PRO USB3 motherboard.
Here is my alsa-base.conf;
# autoloader aliases
install sound-slot-0 /sbin/modprobe snd-card-0
install sound-slot-1 /sbin/modprobe snd-card-1
install sound-slot-2 /sbin/modprobe snd-card-2

I have a strange problem with my sound. The best way to summarize the error is that no two applications can mix their output to the default output channel. When I start my computer, the first application to use to the default sound channel seems to have a lock on the channel. No other applications can use that channel until I reboot again. I can close the first application and still nothing can access that other channel.
When a second application tries to access the default channel one of two things happen. Most application's sound gets routed to the headphone channel. In other cases I get error messages that the device is busy. I suspect that this is a related issue, whenever I use the command line command 'play' I get the following error:
Quote:
ALSA lib pcm_dmix.c1008snd_pcm_dmix_open) unable to open slave play formats: can't open output file `default': cannot open audio device
Now when I restart the drivers using "/etc/init.d/alsasound restart". All these problems are gone. So this is not a major issue, its just a little annoying. So a little information about my hardware/software:
Motherboard: Asus M3N78-VM (onboard sound)
Kernel Version: 2.6.27.23-0.1
Distro: openSuse 11.1
abridged output of /sbin/lspci:

I have an ASUS M5A78L-M LX motherboard with ALC887 inbuilt sound. The sound is barely audible unless the speaker volume is all the way up, and then it is very crackly. The BIOS is set up to use AC97 sound instead of HD Audio, which doesn't work either.
I have tried uninstalling and reinstalling ALSA drivers but it didn't really change anything.
Aplay -l comes up with this:
But still very little sound.

I`m using Fedora 11. I just bought a Creative Audigy Soundblaster sound card. It is recognized by the system, but I can`t make it play sound on all channels in xmms or mplayer. The alsa test confirms that all channels are working - I can hear sound from all of them. I have read several posts in other forums about modifying my ./asoundrc, but they just don`t seem to work.

I recently upgraded to Ubuntu 10.04 and my sound is not working. I have a gateway p-6860FX. i've had this trouble since 9.04 and also in 9.10, but I worked around it by adding the following to my alsa-base.conf with
Code:
Sound worked fine after that, but it doesn't work with 10.04
Here are the results of aplay -L
Code:
I went in to alsamixer and turned everything up. it didn't work.

Something is wrong with the audio on my laptop, when I used the live CD previously, nothing was wrong. It's all staticy when the base comes on or like a beat (I don't know how to explain it). Even ..... vids and such. My laptop audio is not usually like this.

I recently got a new audio interface, which is working perfectly on ubuntu 10.04 i just plugged it in and it worked without any tinkering! the interface is a lexicon omega which is fully supported under alsa. The problem is that for some reason it's not working on ubuntu 9.04 (which is where were most of my work currently is so occasionally i still have to use 9.04 as i don't have all of the same software installed on 10.04).
Jack seems to detect it properly in both 9.04 and 10.04 as it is listed in "interfaces". But it does not show up in "Volume Control Alsa Mixer" so I cannot select it from the drop down list.
So currently I have no sound (just in case you weren't able to decipher that from my primitive ubuntu-speak above )
Here's the output of cat /proc/asound/cards
Code:

I'm having some troubles with my soundcards. I have a Audigy ES PCI soundcard and I just recently bought an M-Audio Audiophile 24/96 soundcard and at the moment I have both of them installed. I'm dual booting w/ Windows xp and I need the Audigy in Windows for gaming and because of the mic input that the M-Audio doesn't have.
First when I installed the M-Audio only Amarok (and probably other 'Phonon' apps) worked but I had no sound in mplayer, xine etc. With some googling I found a way to make the M-Audio card the primary card for Alsa and now mplayer & xine work fine too. M-audio 24/96 uses the module ice1712.Today I noticed I don't have sound in flash player (I use opera, but tried firefox too), and the (alsa?) command aplay won't play any .wavs. Flash sounds used to work okay with only the Audigy installed. I have tried to reinstall the flash player.Aplay -l :

Well I installed Ubuntu 10.10 64Bit along side Windows 7, and I've been unable to get any sounds working, apart from the log on sound. So I tried installing some drivers, and now there is no sound at all, and no sound devices show up in System-Preferences-Sound-hardware
I'm using the on board HD Audio (ALC 889A) and using the optical Audio out for 5.1 Surround sound.
I've tried just using the Stereo ( Green Jack ) out, and still nothing. The suggestions on the on the Ubuntu site, and the following post didn't seem to work either.

I Can't find a great deal of posts with the Realtek HD audio.

I'm running Ubuntu 9.10, but so far I've been unable to get sound to work. I know my sound card is Realtek, because I've had to install the HD Audio Codec Driver when I was on Windows. I downloaded the driver for Linux and it is currently sitting in my home folder. When I tried to Code:sudo ./installthe driver, it failed for the following reason:
Code:
WARNING!!! The mixer channels for the ALSA driver are muted by default!!!

I seem to be having some audio clashes. I use Exaile to play music (if that matters), and after I play music, no sound comes out of videos (not just Ubuntu, it won't work from Yahoo or MSN videos either). Then when I try to go back to playing my music on Exaile, no sound will come out of that. Likewise, if I restart the computer... the sound works again. If I instead watch a video first, there will be sound -- but as soon as I try to play music from Exaile, nothing comes out.

I was running Ubuntu 9.04 and just upgraded to 9.10 recently. I see many others are having problems with their sound. I too do not have sound. I did get sound running briefly with an Alsa update, but it was muffled. In trying many other fixes, I again have no sound and can not resolve it. I am thinking of burning a new cd and doing a fresh install and starting over.
My lap top is an MSI GT725 US model with an HD4850 mobility graphics card. I dual boot between Vista 32 bit and Ubuntu.
Has anyone else had any luck getting the Realtek ATI sound working in 9.10?

I'm pretty much an Ubuntu noob and I'm about to give up. I've spent hours reading tips and tricks to get this sound card working but I usually end up making things worse. This will be my last attempt
- onboard sound is disabled in BIOS
- Delta 1010LT is recognized
- fresh Ubuntu 10.04 32bit install . . . everything is default.
- I know how to access the terminal and for argument's sake, let's say that's it. I need step by step.
I tried to remove all instances of pulse audio in the past and it removed the desktop as well. Talk about frustrating. Ok, so here I am. Fresh install, no sound and I haven't touched a thing.

I have recorded some video, and now wanted to add some sound.I added a sound track, but when it's playing, I can't hear anything.I'm usually running Jack - for Ardour/Hydrogen etc... - I can't find anywhere in OpenShot to change the Audio to Jack, so assume it's not supported.I have killed Jack in the hope that Alsa will work with OpenShot, but still I have no sound.

I have the usual problem of "My sound is not working". I have a few images and my output from:
Code:

Code:
lspci -v
and
Code:
aplay -l
I can't really do anything with the speaker as it is hidden in the case.

i just installed a new Ubuntu 10.10, but i have no sound at all. I google-d for my problem, but i cant find any fix. In sound preferences - everything look great and working - there is my X-fi Xtreme audio CA0110-IBG, and i can choose how many channels to use, but when i go to test button, there are no sound from any channel. I got 5.1 sound system, and i use Flexijack for mic. Im confused, because everything looks like working - the system recognises my sound card, but there no sound at all. I tried to kill pulseaudio, but it not help me.

Recently I installed Ubuntu 10.10 64bit and I have a problem with it.
I have a motherboard with internal audio card as well as I have ATI 2600 card. When I just installed Ubuntu 10.10 sound via motherboard worked perfectly.
But some time later it disappeared. Actually "Output device" that represents audio card disappeared. See screenshot of the Audio Settings dialog.
I made 2 thing - most likely that one of them cause this problem:
- I tried to setup Panasonic Plasma TV as a second monitor via HDMI output of my video card (ATI 2600).
- I added maven-backports repository (new kernel or new audio driver?)
Have anybody seen this problem? Are any pointers how to fix it? If you need any additional info - let me know I'll be glad to provide it.

External slimline HP cd/dvd combo drive
No other optical drives on system
I am having a problem ripping or playing audio CDs on my drive. DVD movies work fine on this drive, but audio cds will not show up in Rhythumbox nor SoundJuicer. Oddly, they will play in VLC.
I wish to rip music to my hard drive. When launching Sound Juicer, I receive the error "no CD-Rom drives found".
