[SOLVED] Internal Microphone on Acer Aspire 1410

Question

My microphone works on Windows but not on any Linux. Its been like this for a while now and I'm tired of using Windows so I'm determined to get my microphone working on ArchLinux. Everything else is perfect... Anyway lets start.
My sound works absolutely fine, my microphone is NOT muted, I have gone through all the steps on the wiki for fixing sound/internal microphones. Yet my microphone is not working. I've tried it on a root account so its not a permission issue either. Here are some outputs, please tell me if anything else is needed to determine the problem. Though I have experience with Linux I wouldn't consider myself an expert, and I know even less about the workings of sound cards.

Thank you in advance, I hope it is something simple that I missed so I can move on with my life.

Answer 1

well I'm not really sure of anything when it comes to this stuff, and this is why I'm here.
But it wasn't working before I started blacklisting things, just followed the wiki and blacklisted stuff that were said to work.
Recently I found a thing on the wiki for Acer One laptops (not mine but similar). It was to compile the alsa-driver with --with-card=hda_intel --with-card-options=hda_codec_realtek
this seams like it should work for me because even on windows my microphone doesn't work (but my sound does) until I install the realtek driver.
But now I have a different problem, aur's alsa-driver, though I can compile it with these options, when it gets to my system it seems orphaned and useless. I don't think my system is using it. Do you know what the reason for this might be? If the compiled "alsa-driver" package will work then how do I get that package to work on my system?
I will take all the blacklists out and reinstall all the sound functionality (starting with the new "alsa-driver". If you can think of anything please tell me.
oh and fyi I believe this laptop has mono-audio, could that be a reason I have only two channels?
