Hello and thanks for your work,

I've just made a new install of lenny had I had since a long time
a problem with the input source selection as the system was just started.
In fact it seems that the input sources is not correctly set. The result
is that although the microphone works (I can hear my voice on the high
speakers if I set the volume to do so) it is not possible to record sound.
It take me a lot of time to understand the cause of this. As setting
manually the input source on CD and then back to microphone solved the
problem, the following command launched at the end of the booting
process solved the problem:

amixer cset iface=MIXER,name='Mic Playback Switch' off,off
amixer cset iface=MIXER,name='Input Source' 1 # select CD as input
amixer cset iface=MIXER,name='Capture Switch' on,on
amixer cset iface=MIXER,name='Input Source' 0 # reselect mike

I suggest whether to add them to the booting sequence or to search
the real cause of the setting's failure.

Regards

Jean-Louis Biasini

Didn't find one
'Input Source' 1 or 0 ???
Mic Playback Switch sounds unreasonabele?

Please tell us which soundcard you use.

Thanks

The same happens to me. Using the suggested sequence of commands allows
recording from the mic.

As Jean-Louis Biasini said, the trick consists in switching the input source first to CD and then back to Mic

I think that it refers to the switch that enables or disables hearing the sound from the mic through the speakers.

Although this symptom can be worked around in the alsa-utils initscript,
it really shouldn't be. Instead, it should be fixed in alsa-kernel.

Please use http://www.alsa-project.org/alsa-info.sh (bash necessary), or
alternately, just attach your SSID (not just vendor and device) from lspci
-vn and full codec information from /proc/asound/card#/codec#.

Thank you. Here is the output of alsa-info.sh:

Do you still need to use your homebrewed script after updating to a
current kernel, e.g., 2.6.32, or using the latest alsa-source?

Yes the problem is still here. The commands:
amixer -c 0 cset iface=MIXER,name='Input Source' 1
amixer -c 0 cset iface=MIXER,name='Input Source' 0

are enough for a work around. Recompiling alsa from sources doesn't
solve this.

If you need more infos please ask

regards,

Jean-Louis Biasini
