[Pkg-alsa-devel] Bug#601727: alsa-base: No sound through speakers on newer kernels

[Jose Manuel Castroagudin]

Package: alsa-base
Version: 1.0.23+dfsg-1
Severity: important

This bug is somehow similar to the one described in the bug report 500162.

If the system boots using a 2.6.30 kernel, everything works perfectly. But,
using a newer kernel (right now, 2.6.32-5-686), some strange things happen: It
seems like there is no sound at all. Every mixer shows all the controllers, and
everything seems right, but you can hear no sound through the laptop builtin
speakers. But I can hear everything if I plug some headphones in (i mean,
through the headphones, not the speakers).

I am not sure wether this is an alsa-related issue, or has something to do with
something in the kernel configuration, or perhaps it is a hardware problem (i
dont think so, because it works using a 2.6.30 kernel...).

Please, let me know whatever you need me to do to make things clear. If you
need some additional information, or want me to follow some steps in order to
try to resolve this issue, or whatever.
