Public bug reported: I have been trying to make my microphone work for a few weeks now. I have a HP Pavilion dv1668ea laptop, with an Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02), which has the Conexant CX20551 codec chip. Neither the internal nor any plugged in microphone works. I tried upgrading to Alsa 1.0.18rc3, but that didn't help. I played around with alsamixer a lot, and tried out all possible setting combinations. Mostly I just get digital noise on the microphone input.
I tested in Windows XP Pro SP3 as well, and my microphones are working there, so it is not a hardware malfunction. The Windows sound mixer has a "Mic Docking Sel"-checkbox next to the "Mic Boost"-checkbox, which must be unchecked in order to make the microphone work. I suspect this option to be enabled hardware-wise in Ubuntu, and I guess lack of an option to disable it keeps the microphone muted. For more information see my tsalsa output: http://nopaste.com/p/aFntL9TKu I am using: Ubuntu 8.04.1 Alsa-driver 1.0.16-0ubuntu4, also tried 1.0.18rc3 I expect the microphone to work, or at least have options in the mixer to make it work, but it doesn't. ** Affects: alsa-driver (Ubuntu) Importance: Undecided Status: New -- snd-hda-intel microphone not working https://bugs.launchpad.net/bugs/282233 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
