Hello, My motherboard: PCCHIPS A13G+ http://www.pcchips.com.tw/PCCWebSite...uID=44&LanID=0 I'm using Ubuntu 7.10 - the Gutsy Gibbon, I was using Feisty before and had the same problems. The interesting thing: the system sounds all work. Some example .ogg files that came with Ubuntu also work. There is one example file however "fables_01_01_aesop.spx" which only gives a very low sound, almost inaudible. The real strange thing happens with ".avi" and mp3 files. They sound distorted and very low, almost inaudible. Some have better/louder sound, but still distorted, but I can understand what is being spoken, others not. I have tried the following approaches without much success: installing the latest ALSA driver from the repositories(this was alsa-driver-hg20071129 at the time I did it.) Then I uninstalled ALSA and installed the latest OSS driver. This helped a bit and the sound was better, but still not perfect, I still have problems with some AVI files. So the last thing I'm trying now is installing the Realtek audio codecs: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false#High%20Definition%20Audio%20Codecs So I downloaded it and followed the instructions. I managed to successfully compile this driver but then when I run alsamixer I get the following error message: alsamixer: function snd_ctl_open failed for default: No such device I read somewhere that this is due to some OSS modules still being loaded and that I have to remove those OSS modules. So how do I do that? Thanks for any help! If you need more information just ask.
