 Posted: Fri Mar 11, 2011 12:56 pm Post subject: making my internal laptop microphone work [solved] |
 |
|
I have an acer laptop with internal webcam and microphone. No problem with the webcam.
On the laptop, I have alsa running well without problem. But I have also a microphone near to the webcam, on the top of the laptop screen.
I issued at making it work (previously, I didn't notice I have a microphone there), but the sound is very very bad in skype (I don't hear my own voice under static). This morning I pushed all the values in alsamixer, this didn't solve that. But now, I have a bad larsen when I close my laptop screen.
So, I may have done things bad, but don't know what at all ! Can someone help me ?
Thanks !

in your kernel config, is snd-hda-intel configured as a module, or built into the kernel?
Often, these sort of issues can be sorted out by making sure you have snd-hda-intel as a module, and then passing the "model=" argument to modprobe, e.g.
| Code: |
modprobe snd-hda-intel model=acer
|
ALSO: On one of my laptops - a cheapy Acer actualy, Aspire 4736z - the internal mic did not work until I updated the BIOS. The only annoying thing about that, I had to boot into Windows to do the BIOS update; fortunately I *do* dual-boot that machine with Windows (need GoToMeeting for work, and it doesn't run under linux -_-), updated the BIOS, things worked fine from that point forward.
...but yes, internal laptop microphones under linux can be a bit of a pain. Actually a major pain - you would almost be better off buying a cheap headset, because external mics do not tend to have this problem. On the Acer laptop I talk about before, I had to use a headset, and it worked just fine - then when i upgraded my BIOS, I no longer needed the headset.

I already have a headset... But I would like my hardware to work !
The last time I tried to update my bios, it didn't issued...
with that options :
model=acer -> have no sound from speakers
model=acer-aspire-7730g -> sound, but the micro doesn't seem to work
model=acer-aspire-7730z (marked on my laptop, I tried...  ) -> sound but micro nothing
The first time (beginning of this topic) I had :
model=auto
enable_msi=1
