Hi, I've just upgraded from linux-image-2.6.32-5-amd64 (version
2.6.32-31) to linux-image-2.6.38-2-amd64 (version 2.6.38-3) and I think
I see the the problem reported by henry atting.
I am also using an Intel integrated sound card (with snd_hda_intel).
To be more precise, with the default configuration (no change in
modprobe configuration) I had the following behavior with the previous
kernel (linux-image-2.6.32-5-amd64 version 2.6.32-31): the beeps used
to be redirected from the PC-speaker to the sound card, so that they
were not audible when the sound speakers were turned off; when using
headphones connected to the sound speakers, the beeps were only audible
through the headphones (this is especially important in a work
environment or office with a number of other co-workers which are not
be disturbed by your beeps).
Now with the current kernel (linux-image-2.6.38-2-amd64 version
2.6.38-3), again with the default configuration, I hear that the beeps
are coming from *both* the PC-speaker and the sound card, which means
that turning the sound speakers off leaves the beeps coming from the
PC-speaker audible and using headphones does not prevent the disturbing
sounds for co-workers.
I tried the following:
# modprobe -r snd_hda_intel
# modprobe snd_hda_intel beep_mode=0
No beep from the sound card, but beeps coming from the PC-speaker!
# modprobe -r snd_hda_intel
# modprobe snd_hda_intel beep_mode=1
Beeps from both the sound card and the PC-speaker!
# modprobe -r snd_hda_intel
# modprobe snd_hda_intel beep_mode=2
Beeps from both the sound card and the PC-speaker! Only the beeps
coming from the sound card are mutable with alsamixer.
Is there a way to obtain the previous behavior (beeps redirected to the
sound card, and configurable through alsamixer, no beep from the
PC-speaker) with the current kernel?
Please someone help me!
Thanks for your time.
