Fedora 14 on acer aspire one netbook mic doesn't work

[brazilinux]

Hi all,

I just found it out now, after installed the skype and tried setup my web/audio on it, the webcam works fine but the mic doesn't work, so i went to the audio menu on fedora 14 and found it out the mic is dead...
Someone had the same issue? Can someone let me know what can i do to fix that?

Thanks!

Run alsamixer -c0 and check the mic is selected as the input device and volume is up.

Can you select the device in Skype? If so check the correct device is selected.

Well, skype just work with external mic. Also the sound preferences just has the option "internal audio analog stereo". I can't run the internal mic. Don't know why doesn't show in skype or the sound preferences. Skype shows "Pulseaudio server".

I kind lost.

Thanks

Run alsamixer as I suggested and press F4, that will show you all the available inputs. Is the internal mic muted or set to low volume?

I did it before, but everything is ok. the mic wasn't muted or set to low volume.

What else can be? I tried read online on google search. I did find a lot people with acer aspire with the same problem. But no answer to this problem.



Well, thanks anyway.

I'm not familiar with Skype but maybe a search on here for Skype and your netbook will find something.

Thanks. But the problem isn't just with skype. But with the linux. Because even the OS can't find the internal mic...

Thanks anyway

See this bug:

https://bugzilla.redhat.com/show_bug.cgi?id=542924

And my work-a-round in Comment#8.

This isn't just happening in Fedora, I've also loaded MINT 9, 10 & Ubuntu 10 all with the same results. It seems to be something with internal mic. I'm running Asus netbook. Tried the alsamixer settings doesn't work but you can see the card its a Realtek ALC 259. I've searched the web & there doesn't seem to be an answer but there's alot of people experiencing the same issue. Turning one speaker down didn't work on my netbook either. Maybe pulse audio needs a linux driver just for internal mics. Attached usb webcam/mic & that works fine. Hopefully, somebody finds an answer soon.

I am also unable to get the microphone to work under Skype. I have tried Dr Diesels comment on https://bugzilla.redhat.com/show_bug.cgi?id=542924 but that doesn't work on my AA1.

I run pavucontrol, and get the volume control window. Clicking on 'Input Devices' gives 'No input device available' when the 'Show:' box (bottom right) says 'All Except Monitors' Changing it to 'All input Devices' gives me the 'Monitor of internal Audio Analog Stereo'

I adjust the bars as per the instructions in comment 8 but still no Mic. The controls also reset once I reboot.

Any help would be appreciated.

There seems to be the same problem on FC12 (with Acer Aspire One). What I did is to select only one channel (left or right) with alsamixer - Capture . This way I got the internal microphone to work. There are some applications that will reset the Left/Right diffrence back to the same level, so the problem might occur later.
Good luck!

[RobinMorris]

Thanks for the reply. I have tried all ways to get the microphone to work. I have set up Fedora to dual boot with Windows 7 on a desktop as well as on the AA1. I get different screens when using the desktop - more bars to adjust etc, but it ain't working on that either. Works on Windows. It looks as if I will need to revert back to Linpus as Skype is essential on the AA1.

I have found a work-a-round for this:

1. Launch pavucontrol (may have to install this)
2. Click on the "Input Devices" tab
3. Turn down the Front Left channel to 0 (make sure they are Left/Right are
not locked) Leave the Right channel at something reasonable, say 80%.
4. Mic should now work

It appears the new Google Voice plugin is resetting this configuration, I have
not found a way to keep it locked at the above.

....
....

This "modified' solution works with my Acer Apsire One ZG5 (AOA150)

Operating System: Fedora 14 XFCE spin

1. Open "Mixer"
2. Click on "Capture"
3. There is a left button that looks like [--]
4. click it so it's "unlinked" [- -] : this will enable you to move each slider individually.
5. Drop the left side of both Mic Boost and Capture to 0 (the bottom) : leave the right side alone.

Testing to see if it worked:
6. Close mixer, and right click Skype (or head to options)
7. Click on Sound Devices
8. Make a test call and follow the instructions

***I recommend you remove (un check) "Allow Skype to Automatically adjust my mixer settings" so Skype doesn't "undo" our modifications.

I can confirm that comment 8 in the bug listed above as well as the text regarding "pavucontrol" works.

Just dont touch the input mic controls in Sound Preferences only use those in pavucontrol.

It now works so thank you all for your comments. I started all over again - back to Linpus, clean USB stick, re-loaded Fedora 14 and hey Presto! I used the pavucontrol method. This time 'input devices' were there, and were adjusted as specified. Again, many thanks.
