What I forgot to mention: before I installed the alsa backport packages the microphone wasn't working either.
I also tested the microphone functionality with the 2.6.32-23 and 2.6.32-22 kernel that I have installed in parallel. For these I didn't install the alsa backport modules. However, even under these kernel versions the microphones don't work. But in the alsamixer panel I can choose between two microphone channels, whereas under 2.6.32-24 there is only one recording channel accessible (but there is a drop down menu for both the internal and external boost). -- Microphone not working on Dell Vostro 1015 https://bugs.launchpad.net/bugs/642948 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
