Hi, I have a Acer Aspire 1420P and according to /proc/asound/card0/codec#0 my soundcard has a Realtek ALC269 codec. HD-Audio-Models.txt tells me that the according model=* option would be laptop-amic. For laptop-amic ALSA finds three microphones (under alsamixer Capture -> Input Source): Mic, Internal Mic, and Internal Mic 1. When I select "Internal Mic 1" as input source (any only then), recording with arecord -f dav works just fine whereas leaving out the -f dav option does not record anything. However, I only have controls for "Mic" and "Internal Mic" but not for "Internal Mic 1" under Playback. I'm using Ubuntu, so the sound should be forwarded to pulseaudio. But pauvcontrol also only lists "Microphone" and "Internal Microphone" but not a thrid one and for these two microphone only noise is recorded. This fact combined with the fact that alsamixer (at least under "Playback") also just lists two microphones lets me conclude that the error is not in pulseaudio but in ALSA. I ran the alsa-info.sh script and you can find the output here: http://www.alsa-project.org/db/?f=90c56b1a344d9c5f3dae7d5d5b04fc8c6094b248 Find the output of lspci -vvnn and the codec graph attached to this email. If there is any other information I should provide, let me know. Thanks for your help! Cheers, Manuel
