Hi allwhat's the result of aplay -l ? it will tell you the chipset.
I have very strange problem with sound. Sound does not work in Debian
Lenny, but works in Debian Etch. Hardware is Toshiba Satellite a30
(lspci in attachment), with sound card ATI Technologies Inc IXP150 AC'97
Audio Controller.
Often the very first time I start playing music after reboot on Debian
Lenny, sound works for certain period of time. Second time xfmedia
hangs, mplayer prints out following in loop:
[AO_ALSA] alsa-lib: pcm_hw.c:405:(snd_pcm_hw_hwsync)
SNDRV_PCM_IOCTL_HWSYNC failed: Broken pipe
This does not happen in Debian Etch.
My first idea was that this is kernel problem. During boot I got
following suspicious messages (full dmesg is in attachment):
MP-BIOS bug: 8254 timer not connected to IO-APIC
..trying to set up timer (IRQ0) through the 8259A ... failed.
...trying to set up timer as Virtual Wire IRQ... works.
[snip]
atiixp: codec reset timeout
atiixp-modem: no codec available
After some experimenting with kernel boot options, I found out that
sound works with option "acpi=off". Other options, like noapic,
acpi={noirq,strict,force}, pci=noacpi, nolapic_timer do not help.
Using acpi=off is not a very nice solution, because it switches off
other usefull for notebook features.
Suspicious kernel messages mentioned above, appear also with option
"acpi=off".
Installing kernel 2.6.29 (from lenny-backports) does not help.
Additionaly 2.6.29 locks up after some time.
I installed Debian Etch on separate partition and there sound works
without any problem. It work with both 2.6.18 and 2.6.24.
So, I installed kernel 2.6.18 and 2.6.24 from Etch in to the Debian
Lenny (just added etch into sources.list and installed). And this does
not help! I got same sound problems in Debian Lenny with kernels 2.6.18
and 2.6.24 from Etch!
So, it looks like it is not a kernel problem. But I do not know where to
look for a problem now and I do not know against which package should I
report this regression bug.
Please put me on CC when you reply to this message.
inspect /usr/share/doc/alsa-base/driver/ALSA-Configurations.txt.gz and
see if the chipset is supported there. next you must put
"model=<laptop-model>" in the config file.
edit /etc/modprobe.d/sound:
options <your-sound-module> model=<toshiba>
a friend have same problem before (toshiba laptop) but with ATI IXP 4x0
(chipset ALC861). but finally sound is working again.
hope this would be a clue for you.
