Asus A8N-SLI mobo sound card
Last modified: 2006-01-11 16:15:07 UTC
Hello I have the Asus A8N-SLI motherboard with the Nforce 4 Sli chipset and the Realtec 850 AC'97 audio codec. Yast->SOUND detects it as K8N4-E mainboard, configured as sound card 0 driver snd-intel8x0 When I click on test I hear no sound. When I try to playback an ogg (I'l submit another bug issue on mp3s) file I hear no sound. Asus provides however some audio drivers for linux here: http://dlsvr02.asus.com/pub/ASUS/misc/audio/ALC850/ALC850_Linux.zip It is source file of the driver. It seems that it is a rather old version of alsa. Unfortunately it has failed compilation. Could you provide a compiled implementation in future SuSE linux versions? After all the A8N-SLI series is a very popular choice for 64 bit Athlon's therefore many other users might have the same problem with me. Ioannis
I downloaded, compiled and installed the drivers from Realtek. They can be obtained here: http://www.realtek.com.tw/downloads/dlac97-2.aspx?lineid=5&famid=12&series=8&Software=True Yet I have no sound. Also yast/sound has changed it's behavior. It displays Nvidia CK804. Configured as sound card number Driver snd-intel8x0 It doesn't display number. Finally when I press anything like edit it crashes. Why? Ioannis
I guess it's a mixer configuration problem. Please attach /etc/asound.state and /proc/asound/card0/codec97#0/* files for debugging. (BTW, mp3 related bugs won't be fixed, excpet for amarok + helix engine.)
Created attachment 60309 [details] for debugging reasons I am attaching the /etc/asound.state file
I have attached the /etc/asound.state file In /proc/asound/card0/codec97#0/* there are two files named ac97#0-0 and ac97#0-0+regs Both these files are empty. (BTW, does it mean that amarok can play mp3s? What is this Helix engine? Is it on the cd?)
The files are not empty but you cannot tar the proc files. Simply update both files separately. I don't see any wrong setting in /etc/asound.state. Which output are you testing? Do you check the output from line-out jack? About MP3: helix engine is a plugin to use the binaries of Realplayer for Amarok, etc. It's (literarlly) illegal to decode MP3 in another way unless you bought the MP3 license. Only a few players support helix, and unfortunately, a bit buggy.

Takashi thank you for your help I plugged some additional cables to my sound card. I had been using the coaxial SPDIF output and I was able to hear in windows. However It seems that I had to plug in the analog cables as well to the sound card as well in order to hear under Linux. Why doesn't spdif work under Linux Ioannis ps: If you wish you can change this status to FIXED
It's partly because Nvidia never released the technical documents. You might enable the SPDIF out by changing 'AC97-SPSA' mixer control to value 0, and turn on 'IEC958' mxier switch. But, it might not work, too...
