Hi
I have an HP 9000 series laptop with an Intel HD sound card and Realtek ALC298 codec. I am having a problem with audio capture ever since upgrading to the 2.6.32 kernel series from 2.6.31. I have git bisected to this commit: 33d78674586aeb6a623b1e612e6f92dd83015ed3 "ALSA: hda - Use auto model for HP laptops with ALC268 codec". After this commit I am not able to capture audio and using alsamixer I am not able to choose the input source. I was using "Front Mic" as the input source when this was working in 2.6.31. I have uploaded my configuration using alsa-info before and after the commit.
Before change http://www.alsa-project.org/db/?f=4f5d3eb02d4d62fa044a4eb0a3aae2614064b208
After change http://www.alsa-project.org/db/?f=a9583da102419a9233cc469259c85ab81645d555
Could someone please provide some help in getting this working, presumably without rolling back the previously mentioned commit? I am not familiar with how the alsa code works but am willing to help out if given some guidance.
This should have been fixed on 2.6.32-rc4. Give it a try. The input source element is gone now for your devices, and the driver chooses the capture source automatically per mic-jack plug.
