HP dv5 mic plays only static in openSuSE 11.1

English Hardware
#1

I have a HP dv5 laptop and the internal mic is not working. I played with a few sliders in kmix, namely Capture and Mux, but these sliders only let in static whenever I try to record something. I remember that in openSuSE 11.0 I had to set the input source in kmix to “Digital Mic”, but I can not find the “Digital Mic” entry in 11.1.

Here is my sound info: http://www.alsa-project.org/db/?f=d60de3f6430a9ba7d3c671d21fd7ebfa7fc650aa

Internal mics are notorious for not working. I no longer bother wasting my time crawling thru the mixer settings in the script print out for an internal mic problem, as the alsa-info.sh script does not give a nice mixer summary (unlike the tsalsa script which does give a good summary) and typically those mics don’t work well anyway .

So basically, my reply is just to say I saw your post (and your “bumps” to the post) but I can not help you with this, and I am replying so that you know your post was observed, but there is nothing I can do about it. You could visit IRQ freenode channel #alsa, or if you have no other luck, write a bug report on openSUSE and on alsa.

Reference the 11.1 mixer, note you can go to a menu item (channel ? < not sure > ) to add extra mixer entries.
