Hello,
I've been trying over a period of months to get reliable operation of
alsa on an HP Omnibook 5500CT. I'd like to use this system as the
playback for .mp3 files stored on another system on my network. I've
updated everything I can think of, and the problem is pretty much
unchanged. I started with Debian 2.2 stable (potato) with kernel
2.2.17 and the Debian stable package of alsa 0.4.1i. I'm now running
Debian "testing" with kernel 2.2.19 so I could get a gcc new enough to
compile the latest alsa stable drivers.
When it is working, the system sounds fine. Currently I am using
mp3blaster to repetivily play a song list of about 40 songs. Sooner or
later, anywhere from a few minutes to several hours, the sound stops
playing right in the middle of a song. Nothing else is affected, the
mp3blaster keystrokes work, and all the other functions of the
notebook are fine, i.e. network, screen, keyboard, other virtual
consoles. The speaker still beeps, and that is going through the mixer
in group Mono. When the PCM sound channel is hung, changes to the
SPKR/Mono channel volume using the mixer controls in mp3blaster don't
work, but the speaker still beeps at the volume it was proviously set
to. If I exit mp3blaster, and execute 'saytime', no sound is produced.
When the PCM channel is hung 'saytime' takes just over 10 seconds to
return to a shell prompt with no sound or errors produced. When the
PCM channel is live, 'saytime' takes about 4.5 seconds to voice the
time and return to a shell prompt.
There are no errors printed or logged. To restore sound operation, I
have to do a system shutdown and completely remove the power or do a
hardware reset, a reboot is not sufficient. This would seem to
indicate that the sound chip is in some strange state and needs to be
powered down or hardware reset to get a full reset.
The hanging is not dependent on any particular application, it also
hangs with mpg123 with a playlist. I've tried both smbfs and NFS to
access the server, currently using NFS with 8192 size buffers. Tried
two different brands of network cards. All APM is turned off in the
kernel and in the 5500CT's bios, except for the hard disk spin down in
the bios after 3 min.
System details:
HP Omnibook 5500CT
Bios 2.16.0
Pentium 133
64Mb ram
10/100 Linksys network card
CS4232 sound chip
Debian "testing" with locally compiled kernel 2.2.19
gcc 2.95.4-6
libc6 2.2.4-1
pcmcia compiled from source 3.1.29
alsa driver 0.5.11
alsa library 0.5.10b
alsa utils 0.5.10
I don't think there are fundamental issues with the setup, otherwise I
would not be getting sound at all. I've tried many different
parameters for the sound card. None have worked any different or
better than the others. Currently I am using the "preferred" values I
found in /proc/isapnp.
Here's the section from /etc/modules.conf

At this point, it would seem that there is a very low level problem
with the driver.
Any help with this would be greatly appreciated!
Thanks,
Denny Fox
