I guess alsa and /proc are all fine on my machine, but I've got a
blank result on /proc/asound running following find, no sure if that
was significant:

[asound]$ find . -type f -exec echo {} \; -exec cat {} \; > /tmp/asound

$ rpm -qa | grep -i alsaalsa-utils-1.0.14-3.rc4.el5

]$ rpm --verify  alsa-lib-1.0.14-1.rc4.el5.i386
alsa-utils-1.0.14-3.rc4.el5.i386 | echo $?

[asound]$ ls
card0  cards  devices  Intel  modules  oss  pcm  seq  timers  version

[asound]$ pwd && cat modules && cat cards /proc/asound
 0 snd_hda_intel
 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xf0500000 irq 66

I've also tried to ls in /proc/asound/Intel:

$ ls
codec#0  codec#1  id  oss_mixer  pcm0c  pcm0p  pcm2c

Seems, all drivers there, is there any command such as cat to verify
low level drivers by playing a sound?

Thank you.
