Default Bug#514260: linux-image-2.6.26-1-amd64: kernel does not support multiple, not similarm soundcards

Hi Ben,

Thanks for the reply.
Situation is as follows:
my motherboard has an onboard soundcard. I own several PCI card soundcards. I tried them all, all to the same result. If I have besides the onboard card one PCI soundcard in the system (so 2 soundcards in total) the sound system does not give a sound at all on any card. All mixer settings are lost. I have to run "alsaconf" on every occasion to enable sound on the onboard card. IIRC (but it has been a while since I tested) sound on the PCI cards never works.

The issue seems to be driver related as dmesg contains errors before I do a thing. I think the issue kicks in the moment the driver for a PCI card is loaded and it starts conflicting with the onboard card.
On the first releases of 2.6.26 stock kernel things worked fine. All kernels since then / up till now have this issue including the kernel currently shipped with Lenny.


Regards
Olaf

Sorry for the delay in answering your bug report.

Do you mean that mixer settings are not correctly restored to two cards

of one type?



Ben.

What do you mean by "all kernels since then"? The Lenny kernels or did you
already try later versions?

The next release of Debian (6.0, code name Squeeze) will be based
on 2.6.32. Please test the current 2.6.32 from unstable and tell
us whether the problem persists.

The 2.6.32 kernel is available from packages.debian.org and can
be installed in both Debian stable, testing and unstable
installations.

Thanks,
Moritz

Default Bug#514260: linux-image-2.6.26-1-amd64: kernel does not support multiple, not similarm soundcards

Hi

"all kernels since then" : all kernels released under Lenny. I have not tried newer kernels from outside of the Lenny repos. I am a bit reluctant to do so as it usually requires other packages such as udev and libc to be upgraded too and therefor can have a serious impact on the stability of a system. If it would be just the recompilation of the Vmware-server2-wrapper I am running it would be fine. But I am not looking for a cascade of dependencies. Could you please comment on this?


Thanks in advance,
Olaf

No, it is the contrary : new udev (and perhaps libc) requires new kernel. But
new kernels do not require new udev/libc. So you can try to install only
the new kernel (and perhaps firmware packages if your hardware need them).
And if something does not work, you only have to reboot and select your
previous kernel at grub time.

Vincent
