Playing a wav file through alsa pcm device generates a quadruply repeated short sample (about 0.25 seconds), so instead of the data being output 1234... I get 1111222233334444... if you see what I mean. Reducing the value of the --buffer-size= option to aplay can shorten the sample time, but not the repeat effect. Hardware: Acer Aspire 1501LMi laptop, 512M Ram, 1.8GHz cpu. (Athlon64 3000+) Kernel 2.6.5-gentoo-r1, although it also did the same on kernel 2.6.3-gentoo-r2 Playing sound direct from a CD is correct (this does not use the pcm input). $ lsmod Module Size Used by cpufreq_userspace 5152 0 snd_pcm_oss 58340 0 snd_mixer_oss 18816 1 snd_pcm_oss snd_via82xx 23296 0 snd_pcm 97100 2 snd_pcm_oss,snd_via82xx snd_timer 22216 1 snd_pcm snd_ac97_codec 64900 1 snd_via82xx snd_page_alloc 10632 2 snd_via82xx,snd_pcm snd_mpu401_uart 6592 1 snd_via82xx snd_rawmidi 21472 1 snd_mpu401_uart snd 49192 8 snd_pcm_oss,snd_mixer_oss,snd_via82xx,snd_pcm,snd_timer,snd_ac97_codec,snd_mpu401_uart,snd_rawmidi sg 25328 0 ide_scsi 14724 0 radeon 110048 0 yenta_socket 15360 0 ide_cd 38536 0 sr_mod 13540 0 cdrom 37160 2 ide_cd,sr_mod Removing snd-oss-pcm module has no effect. I have tried adding options snd-via82xx dxs_support=2 to /etc/modules.d/alsa to no avail. Booting to a 32-bit installation running 2.4.23 kernel works correctly.
odd. I use via82xx as well, but i had no problems throughout 2.6 series starting from 2.6.0-test9. Please provide output of grep SND /usr/src/linux/.config | grep -v "#"

Compile in the above and it should work for you flawlessly... Good luck ! If it works, please tell us here, so that we can close this Bug. ;-)
Sorry, using the sound drivers hardwired into the kernel makes no difference. Roger.
