Bug Description

Sound and webcam works perfectly. I cannot use the microphones of my Laptop, however the line-in is working. This means when I play music on my laptop and use line-in, I can record it. Using the microphone, sound-recorder does even not start recording.

Everything is unmuted. It works fine with the Ubuntu Live CD. As soon as I install Ubuntu I encounter this issue.

In order to fix the issue I had to add the below line into /etc/modprobe.d/alsa-base.conf

options snd-hda-intel position_fix=1

Mic volume works correctly under sound recorder now

Do you still need this quirk (position_fix) if you use the latest daily build of the sound drivers? https://wiki.ubuntu.com/Audio

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed' to 'verification-done'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
