I have installed gentoo and all kernels up to 2.6.7 work just fine with audio, but kernel 2.6.9 does not. I belive this is a kernel bug as Suse Linux 9.2 with kernel 2.6.8 also does not work. Reproducible: Always Steps to Reproduce: 1.Install kernel 2.6.7 and get sound working 2.Upgrade to 2.6.9 Actual Results: Sound stops working with no errors. Programs use /dev/dsp as normal but no sound results. Expected Results: Sound plays!

post your `dmesg` output
are you using emu10k1 or snd-emu10k1? That is, are youu using the alsa or oss drivers. Please post your .config, lsmod output, and dmesg output.
Created attachment 46798 [details] dmesg lsmod /var/log/kernel/current /proc/config.gz I have attached a text file with four sections. DMESG LSMOD /VAR/LOG/KERNEL/CURRENT .CONFIG (from /proc/config.gz) Also I am using snd-emu10k1.
can you try disabling alsa in your kernel and using media-sound/alsa-driver-1.0.7-rX?
can youu please try alsa-driver-1.0.8_rc1 and if it's still a problem report upstream as well
I have rebuilt my 2.6.10 vanilla kernel without alsa and used ALSA_CARDS="emu10k1" emerge alsa-driver and now sound works. So there must be some kernel problem. Also, I saw that the -ac9? patch set seems to include an alsa fix witch may or maynot fix it. So, it is only a work around. The issue still stands.
marking fixed since the prefered method for installing alsa (alsa-drivers) works.
