Bug Description
Binary package hint: alsa-base
Hi!
I'm currently trying to get the mic to work an a friend's Toshiba A100. First I installed Ubuntu 9.04 and tried to record using audacity and the audio-recorder but had no luck. Then I upgraded to 9.10 (Alpha 6) but that didn't help. Within karmic, audio-recorder even crashes on exit and sound playback is a little bit choppy and strange noises occur when switching between windows or minimizing/
The weirdest thing about this bug is that is does NOT occur when using the live system! I tried both 9.04 and 9.10 A6 live CD and succeeded to record and playback my own voice using an external mic (there is no builtin mic). But after the installation the mic stops working! Because of that, I believe that it's a configuration issue rather than a bug within the driver. I checked that the selected input-device is correct and not muted (using alsa-mixer). I also commented out all options within alsa-base.conf (hoping to reproduce the settings from within the live session) but it did not help. Does anybody have some suggestions?
Here are some error messages from dmesg that may be helpful:

After talking to people in https:/ /bugs.launchpad .net/ubuntu/ +source/ alsa-driver/ +bug/391114 and doing some search I've got some news on this. The option "probe_mask=8" fixed the problem with the crackling sound and the timeout errors from above, at least it seems so... Furthermore, alsa-mixer shows all devices correctly (capture devices were missing before). At the first glance, everything seems correct now...
However, one problem remains: recording STILL doesn't work! When recording with audacity, the time-slider doesn't move forward but is constantly flickering. And when using GNOME's sound recorder, recording stops immediately after starting it and the app crashes on exit each time. PA's "volume meter" for recording doesn't show anything either. I'm running out of ideas right now...
