Hi Sir, I am enclosing the also-info for your reference. Thanks.
The mixer connection looks ok. Please, enable the "Front Mic" in alsamixer (mute & increase volume). If it does not help, try keys 'z' and 'q' to disable left channel (inverted phase issue). Please, attach the alsa-info file in configuration with Front Mic enabled (in mixer configuration you believe it's correct).
Hmm, solution is simple. 1. Run "alsamixer", 2. press "F6" for select sound car. 3. Select HDA Intel. 4. Then press "F4" 5. Use your's arroes (left and right) and setup volume on all your microphones. :) I have a similar hardware. Soundcard: HDA Intel Chip Conexant CX20561 (Hermosa) Output lspci: 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) And some statistics: Pulseaudio: 0.9.22-5.fc15 (i686) Alsa-firmware: 1.0.24.1-2.fc15 (noarch) I hope I helped. But, still is a bug.
Created attachment 516049 [details] alsa-info with Front Mic enable Hi Jaroslav Kysela, Could you help to check the attached alsa info? I run alsamixer, then there a front Mic in the playback option, I unmuted it. Thanks. Hi Hufis, There is only "capture" under the F4 option, it is unmuted. I suspected I will have Line-In,Mic-In in it. I think it would be another issue. Thanks.
