ASUS A7N8X-E Deluxe Soundproblem: modules (snd_intel8x0) loaded but sound is playing only one second
Hi all,
I am searching the HOWTOs, WWW and logfiles since a few days now
trying to find a solution for my problem.
I have an ASUS A7N8X-E Deluxe Board running Debian GNU Linux. The boot
CD loads the OSS i810_audio module which is working quite fine (don't
know if 5.1 multichannel is supported with that driver). I configured
the ALSA modules in the 2.6.7 kernel. The modules are loaded
correctly:
snd_pcm_oss 58280 0
snd_mixer_oss 19456 1 snd_pcm_oss
snd_intel8x0 29960 0
snd_ac97_codec 66948 1 snd_intel8x0
snd_pcm 94116 2 snd_pcm_oss,snd_intel8x0
snd_timer 23044 1 snd_pcm
snd_page_alloc 9864 2 snd_intel8x0,snd_pcm
snd_mpu401_uart 6784 1 snd_intel8x0
snd_rawmidi 21952 1 snd_mpu401_uart
snd_seq_device 7048 1 snd_rawmidi
snd 50020 9
snd_pcm_oss,snd_mixer_oss,snd_intel8x0,snd_ac97_codec,snd_pcm,snd_timer,snd_mpu401_uart,snd_rawmidi,snd_seq_device
soundcore 7648 1 snd
But when I start xmms or mpg123 the file ist only started and stopped
after less than a second. I can repeat this several times.
After searching the log files I found out that IRQ conflict could be a
problem. IRQ #5 is used 3 times. With the default installation Kernel
(2.6.6) and the OSS driver the sound card has IRQ #20.

Could someone please help me out with my problem. I don't want the OSS
driver because the ALSA driver has better suport as far as I know.
Thank you,
Christian
