    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.
    Below you see the output of lspci -vv:

    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
