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
alsa-lib-devel-1.0.14-1.rc4.el5
alsa-lib-1.0.14-1.rc4.el5
]$ rpm --verify alsa-lib-1.0.14-1.rc4.el5.i386
alsa-utils-1.0.14-3.rc4.el5.i386 | echo $?
0
[asound]$ 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.
Jim
