OpenSUSE Hardware :: Distorted Audio - Unless At 50 Or 100% - Nvidia Nforce2 AC97

Dec 19, 2009

I've gone through the process of installing and setting up OpenSuse, which has been fairly streamlined.

The only problem I am having is with my Soundcard the audio coming out of it is highly digitally distorted unless I set it to 100% or 50% in the sound preferences section. Once this is done, the audio quality is still fairly awful, but doesn't sound like my guitar's fuzz box!

I'm assuming this is some sort of drivers issue and I have a few options in my yast audio configuration that I'm unsure what to do with.

They are as follows:

Now, these options are all able to be given a numerical value, first question, what do they stand for and what does the value do?

And second question, does anyone know what a semaphore is in relation to audio codecs? I have worked with audio for years and never some across this termanology?

Ubuntu Multimedia :: No Sound In 10.10 With NForce2 AC97 Onboard Audio

Jan 14, 2011

Over the last few days I've been spending some time converting my headless web server into a media center running Boxee for our lounge.

I have managed to get *nearly* everything working with the exception of sound. The computer has onboard sound, both front and back ports, and I tried every combination of outputs and plugs.

I also checked it wasn't muted, or anything like that.

So, I wasn't able to get it working with the stock Ubuntu 10.10 stuff - I turned to Google and found a thread which suggested I download and install this.

I ran the ./install as root, and it took about 3 minutes to install everything. Rebooted and now I'm left worse off than before - this time I actually have no sound card even listed.

I've been thinking some more, and after another hour or two reading through random threads, I think it may have been a mistake to install those drivers.

I couldn't find a way to uninstall them, so I've been reinstalling all the alsa and PulseAudio packages I can find with no luck.

Now I'm stuck with doubly no-sound.

If I can't get onboard working then I'm considering buying a new graphics card with HDMI out (the current one has a hard time with Boxee), or maybe a dedicated sound card instead.

Ubuntu Multimedia :: How To Prevent - Using AC97 Audio

Mar 12, 2011

I have an M-Audio Audiophile 2496 card installed in my PC. It is of far higher quality than the AC97 sound built into the VIA chipset. I want to use the M-Audio card so AC97 sound is disabled in BIOS.

When using Audacity I can record and play with the M-Audio card as I wish.

When using VLC (or any other media player), Ubuntu insists on playing through the AC97 ports - which I have disabled and which, I would have thought, was a pretty good indication that I don't want to use them.

Even when I configure VLC to use the M-Audio card (using VLC's <tools> <preferences> <audio> <output Device> ) it still plays through the motherboard via-82xx hardware.

What nonsense is this? Surely Ubuntu cannot require me to replug my speakers when I want to switch between VLC/ Brasero etc and Audacity?

I looked at the Pulse Audio apps: good grief! Is there any human being which understand what all that is supposed to be about? I could find nothing which matched my understanding of my hardware or related in any way to what I, as an end-user, want to do with my system. Is there an interpretation of this PulseAudio function available anywhere?

Fedora :: Audio Output Distorted In F15

Jun 4, 2011

I have a problem with the audio output in Fedora 15. It seems 'dirty' to me, like with a lot of distortion. I use for the output a nice USB DAC that seems to run very good with Ubuntu and Windows, strangely with Fedora isn't the same. I say strangely because the sound pipeline must be very similar to that of Ubuntu, no? Kernel, ALSA, Pulseaudio and so on. How could I improve mine audio output? Tried with Flash videos and Audacious audio player. Lowering audio output (like to 50%) greatly improve audio quality! Why is permitted to the system to go over and distort?

Ubuntu :: Distorted Sound When Plug In Audio Jack

Mar 15, 2010

I am running Karmic (9.10) on an MSI U120 Wind. I dislike netbook-remix but that is beside the point.

Last night I made the biggest mistake of my life which is causing a loss of still counting hours. I decided to do an update, due to having enough bandwidth, and security updates to download.

So it finished, and I went to sleep.

This morning I went to plug in my speakers to the audio jack so I can listen to music loud, and it was all distorted. I changed al 8 or 9 volume controls and nothing. I unplugged the wire from the audio jack, and the sound is perfect on my netbook's speakers.

I have tried different wires, speakers, editing config files, removing and purging related packages, and nothing works...

I have been google-ing for hours and everyone seems to have the same problem, but all of the supposed fixes do not work for me...

Here is a pastebin of my Alsa info : [URL]

I fear switching back to winblowz..

OpenSUSE Hardware :: HDMI Audio Nvidia GTS 450?

Jul 29, 2011

I have a Nvidia GTS 450 GPU with HDMI. I want to have the audio on my TV that's connected with HDMI cable. But for some reason I'm not able to get the audio working. The card has its own audio chip. In Yast and pulseaudio I can see the card. But when I select it for playing audio it will not play on my TV.

Changing the cable doesn't work and don't know what to do. Every thing on the internet I have tried doesn't work. Here are some settings (if you need more just ask): Using openSuSE 11.4

cat /proc/asound/cards
0 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xf7f78000 irq 21

OpenSUSE Hardware :: No HDMI Audio On NVidia GeForce / NForce IGPU On Mb ASUS P5N7A-VM 11.2 Or 11.3?

Aug 6, 2010

I have an ASUS P5N7A-VM motherboard and was using Optical out for sound without issues running OpenSuse 11.2. I then got rid of my receiver and wanted to just use HDMI sound. I couldn't get it to work so I upgraded to OpenSuse 11.3. I simply went to the Sound control panel applet and changed it to Internal Audio Digital Stereo (HDMI). I can not get any sound from it on OpenSuse 11.3 either. I have ran sound tests from the command line "speaker-test -Dplug:front -c2 -l5 -twav" which all run without errors, but nothing comes out of the speakers. I have ran the suggestion of one post "" and here are my results: I have also tried the following post which did not resolve the problem since it seems to be Ubuntu based. I have undid everything from the post as well to make sure I don't stray to far from normal.

OpenSUSE :: Graphics On My Computer Becomes Distorted

Jan 15, 2011

For some reason or the other, after some time the graphics on my computer becomes distorted. I had this issue before reinstalling my operating system, I thought that reinstalling the operating system would fix these issues, but they still remain.

Also, I never encountered this issue before upgrading from openSUSE 11.2 to openSUSE 11.3. Of course, restarting my computer fixes this issue.

An example of what I am talking about can be found here:

openSUSE 11.3 64-bit

OpenSUSE :: Distorted Fonts With Desktop Effects?

Apr 11, 2011

I'm getting this weird behavior when I have Desktop Effects enabled. When it is on, it's like there are two or three vertical and horizontal lines running across my screen that distort any of certain font characters that are under them. In some cases these characters are trimmed slightly, in others they have an odd skew to them, and in still others the letters are completely removed/missing/invisible. With Desktop Effects disabled, everything appears as normal. I have attached a screenshot in which you can see there are at least three letters missing from the left side (Desktop Effects enabled) and not from the right side (Desktop Effects disabled). There is a missing 'l,' a trimmed 't,' and a distorted 'p.' I'm on a one-week-old 11.4 install with nVidia drivers installed from that repo.

As far as I can tell, Desktop Effects works with few other issues, although there are some aggravating ones (having to click task tray items multiple times to get a response, multiple windows highlighted in the menu bar as though they all had focus, etc) that I will look into once I get this one key issue taken care of.If any other diagnostic information might be useful, please let me know and I will provide ASAP.

OpenSUSE Install :: 11.4 64bit - Screen Distorted ?

Apr 12, 2011

First I tried to install suse 11.4 64 bit from the Live CD, but when I tried to install, the screen was totally distorted (only the mouse pointer was possible to see with no problem).

So I tried to install from the DVD. This time the graphical of the installation worked perfectly. So i installed KDE. (the .iso is perfect, i used the md5) Everything normal until the Login screen, again is totally distorted, and can observe only the mouse. But I could log in normally just typing the password and pressing enter, it made ‚Äč‚Äčthe normal sound of suse opening the session, but remained totally distorted the image.

My computer is: HP Pavilion dv6000 - AMD Turion X2 64bit, with NVidia chipset (GeForce 7150M / nForce 630M). The suse 11.3 64bit was operating normally, with the NVidia drivers, but i installed some package that kde did not work anymore. So I decided to install 11.4.

OpenSUSE Multimedia :: Encoding Video For DVD - Distorted Sound (AC3)

Aug 1, 2011

It is well known that mencoder can be used to encode video to be burned on DVD with a tool like dvdauthor. The whole procedure is described here:
7.8.†Using MEncoder to create VCD/SVCD/DVD-compliant files

Sound for a DVD is normally encoded with AC3. I encountered some cases where the encoded sound was badly distorted. As it seems, the default for the input changed to float at some point. The fix for this is to use:
instead of "acodec=ac3".

Ubuntu Installation :: No Sound In 9.1 With AC97

Hardware :: No Audio With Nvidia GTS 450 ?

Dec 27, 2010

I'm trying to get audio over HDMI.

I can't seem to get the Nvidia card to show up as a sound card.

System Info:
Debian "Sid"
kernel: 2.6.32-5-amd64 (2.6.32-29)
alsa: 1.0.23+dfsg-2


I've tried adding "options snd-hda-intel enable_msi=0 probe_mask=0xffff,0xfff2" to alsa-base.conf, variations of those options don't seem to have any effect, or sometimes break the ATI audio.

OpenSUSE Multimedia :: 11.1 Updates To Pulse Audio In Gnome Improve Audio Functionality ?

Oct 17, 2010

I'm thinking of installing openSUSE-11.1 Gnome on a Fujitsu-Siemens Amilo 7400M laptop because the wireless in Gnome is much more user friendly than KDE3/KDE4 in openSUSE-11.1. The idea is to give this laptop to my 84-year old mother and things need to 'just work' for her (she currently has a desktop running openSUSE-11.1 KDE3 that uses a WIRED interface to the web).

I refuse to update this laptop to openSUSE-11.2 nor 11.3 (nor other recent distributions) because every kernel update after the 2.6.27 kernel has broken the Intel i855GM graphics drivers for that laptop. There are many bug reports and none have fixed the problem for this Fujitsu-Siemens implementation of the i855GM graphics.

Hence I am looking at Gnome.

I booted the laptop to a Gnome openSUSE-11.1 liveCD and wireless is easy and works great. But audio is very very VERY bad. It is incredibly user unfriendly and it does NOT work well. I assume that is because pulse audio in openSUSE-11.1 was very immature.

I note these updated packages in the openSUSE-11.1 update repository:


So my question is, did the updates to pulse audio (in the openSUSE-11.1 update repository) fix the pulse audio situation? Are there ANY helpful views on this?

Currently my wife is using this laptop with KDE-4.4.4 (and openSUSE-11.1) so I can't just install Gnome and play with it without taking the laptop away from her for a while (note the hard drive is too small for a dual boot of KDE/Gnome).

OpenSUSE Multimedia :: Audio Choppy - Can't Play Any Audio With Amarok When Desktop Effects Are Enabled

Jun 7, 2011

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.

Ubuntu :: NVIDIA No Audio And Linksys WMP600N

Feb 13, 2011

I tried out ubuntu and I was beyond impressed with this OS. I decided it was time to do a complete migration to ubuntu. I installed Ubuntu 10.10 on my HP laptop and everything went great. It detected all the drivers and my laptop is working in tip top shape. I decided to install ubuntu on a custom PC I recently bought (used for Java development), and that is when I started to run into problems. These are the specs on my custom pc:


I am using Ubuntu 10.10 64-bit edition on the system. First problem I am having is there is no audio on my system. For this card I'm using an HDMI cable to connect it to my screen. I installed the NVIDIA proprietary drivers and there was no audio. I reverted back to drivers I found on the NVIDIA website and still there is no audio. Second problem I am having is attributed to the wifi card I am using (I think). I keep getting this message on boot after post (and on the terminal after I switch off the X server by stopping gdm):


However, after the system boots I can connect to the internet.

OpenSUSE Hardware :: 2 Audio Cards - How To Redirect Audio Streams

Feb 7, 2010

on my PC I have 2 sound drivers, one from the mainboard (AC97) and one PCI card (ES1969). Because the mainboard sound path did not recording, I installed the PCI sound card and with 11.1, I managed it to play and record all audio data. With 11.2 the PCI sound path plays the system sounds (suse start-up or shut-down sounds) but not the streaming audio data (skype, flash player). But these are played by the mainboard audio instead. The audio-tests from yast->hardware->sound work for both paths. How should I configure the system to redirect the audio streams to the desired (PCI) audio path? The PCI audio is set as primary sound card and is not muted.

Ubuntu :: Nvidia 570 GTX Evga Won't Play Audio Over HDMI?

Jan 14, 2011

I recently built a new computer and got an evga 570GTX (Nvidia)I was using windows 7 pro that I got for free from school (MSDN or something) but it was crashing every 5 minutes. I could get on a play a game for 4 hours, but cuz cursing around or surfing the web was crashing all the time. Complete freeze. Couldn't start the task manager, number lock and caps lock jammed ect...

I was starting to think it was my MOBO failing because of the reviews until I installed ubuntu and everything was fine, no crashing no bull$#!7 no evil sauce.

Only problem was I installed 10.04 and fought it for a day with no luck installing the graphic card drivers but today I installed 10.10 and it picked up the nvidia drives right away.

Now the only problem I am having is audio.

In Windows I could play audio over the HDMI cable but in ubuntu I cannot.

I've tried using a headphone cable and that doesn't work either, and I know it's not the cable or the green sound port on my MOBO because other speakers work in the port, headphones work, all the cables work ive tested them on other computers and speakers and in cars, so the only thing left is the OS. I want to be able to play audio from the computer over the hdmi cable to the TV.

I've played around in the sound settings for hours... NOTHING.

I dont get how something as simple as audio over HDMI or a headphone jack/cable can be done by windows and not UBUNTU!

Ubuntu :: Nvidia Audio Stops Working During Playback?

Feb 13, 2011

I have the nvidia sound card built into my motherboard. Just a few hours ago it started to just stop making any noises what so ever. I rebooted but to no avail. I finally was able to find a fix by purging pulse AND alsa, then reinstalling them and rebooting. The problem is this will only allow my sound to work for about 10-15 mins. Kinda hard to watch "'Neath the Arizona Sky" if you gotta reboot every 15 minutes or so...

I have also purge and reinstalled ubuntu-desktop and that will work temporarily and extend me out another 10-15 mins from when it stopped, but then I still have to reboot.

I am using 10.10 Maverick 64 bit and have been using it for a while, this is the first time this or any other problem has occured.

I have been through the forums and checked every thread I could find with a Bingle search that was in any way related to random sound stoppage. I have tried most of them (did not try the ones that were specific to other cards as far as editing the .conf's for those cards)

Ubuntu Multimedia :: Audio Over HDMI With NVidia Card?

I compiled and upgraded to newest alsa, so my HDMI audio shows up as one of the sound cards. I also read that I should manually unmute everything that shows up in alsamixer that is related with the NVidia card, and I did that as well. Unfortunately I still don't have any audio.. Here's the output of aplay:
