Hi, I'm using Mandriva kernel 2.6.29-tmb-desktop-2mdv, which according to the changelog contains Alsa 1.0.19+ snapshot 20090327 and Alsa 1.0.19+ unstable addons snapshot 20090327.
With this kernel, I have no sound working on my Intel HDA device on a Dell Latitude E6400 system, while sound is working fine with standard 2.6.29 kernel.
aplay gives this output: ALSA lib pcm_dmix.c:1008:(snd_pcm_dmix_open) unable to open slave aplay: main:590: audio open error: No such file or directory
According to strace, this is because of a missing /dev/snd/pcmC0D0p. # ls /dev/snd controlC0 hwC0D0 hwC0D2 seq timer
