Comment 136 for bug 278648

@c4pp4:

I have a Fujitsu-Siemens V5545 using a Conexant CX20549 (Venice) chipset. I applied your patch but the microphone is still not functional. When using the "lenovo" model the input devices disappear from my list of devices as shown by "alsamixer -D hw:0".

When using the "laptop-hpsense", "laptop-micsense", "laptop-hpmicsense", "benq", "laptop-hp530" models, and AFTER I unmute and raise the volume level for my input devices inside "alsamixer -D hw:0", I can hear some crackling noise coming from my laptop's speakers when I plug / unplug my external microphone. Even so, the microphone does not appear to actually work - trying to record something in Audacity results in silence (actually in a slight "digital equipment"-like noise).

When using the "test" model and after raising the volume level for all devices I can find in "alsamixer -D hw:0" I can't even hear that crackling noise...

What do you suggest I should try next? I'm not work-shy and don't expect solutions to be delivered on a plate, so please do tell whatever you have in mind.
