Comment 7 for bug 441502

I loaded the 4.9 upstream and 1.15 BIOS from ACER. Bug still exists.. Please let me know what to do next. My internal microphone has static and I want to use a headset and then eventually a plug splitter of microphone and headphone.
The headphones work.
The microphone does not work
Both work fine in windows (sorry).
I have pauvolume control and it does not list a secondary input device.
I tried hdajackretask and it also did not seem to work.

According to what I know.. The internal microphone should be muted and the external should work..
That happens to the headphones and speakers respectively when you plug it in.

Please advise. Maybe you can help me figure out the "advanced settings" for hdajackretask and then it can go into the builds for the next rc.
