Microphone stops working after some time

[misiu369]

The whole idea was to restart pulse in the terminal with verbose output so we could see the error messages.

Here's the info in Polish - if you need any part translated, let me know which:

Choose the upload option and provide a link for the output.

Here it is, made after some time, when mic wasn't working any more.
If you need it made right after reboot when everything works or after restarting pa, let me know.

Btw, thanks for your help!

Pulse output looks fine (Google Translate)
How much have you fiddled with alsa-base.conf? Have you tried without the MSI switch, or setting it to 0? How about 'mobile' or 'touchsmart' model?

Tried only "options snd-hda-intel model=laptop" and adding "enable_msi=1" or "enable_msi=0" to it. So I should try with model=mobile and modol=touchsmart, instead of laptop? (can't today, but I'll try tommorow)

Btw, lately I had to skype, so after reboot I didn't run anything else and mic worked for a long time. Twice I did that actually - once I've killed mic by running world of warcraft through wine+winepulse. second time I tried different browsers (chrome, opera, ff) with and without flash but that didn't kill the mic - however running thunderbird did. That was unexpected.

Is there any way to take a closer look at what happens when the mic dies? Syslog is no help, but maybe there's some debug mode in pulseaudio?

Probably the easiest thing is to use the 'log file viewer'. It may not be in the default install:

sudo apt-get install gnome-system-log

You can launch it from the administration menu.
Another thing to try is the pulse command posted previously. Simply leave the terminal open. It should report any errors (for pulse) when it re-occurs.

Hey guys, I have exact the same problem.
I have a webcam, microsoft LX-3000 headset and motherboard's sound card. If I select an input from either of the above, it works ONLY for 3-4 seconds and then it stops! Really strange! Any ideas ?
