Fixing microphone for Skype in Peppermint 2

[BkS]

I've read the tutorial for fixing the microphone in Skype. However that fix doesn't work for me sadly. I do see a bunch of options for the microphone in the Options > Sound devices menu.

Currently the built-in mic is just recording static, but if I plug my headphones in with a microphone, I hear nothing from that mic.
I'm supposed to be helping a guy fix his Windoze machine atm, haha so some assistance would help here.

Everything I can list is below:

Do you remember doing this:
http://linuxforums.org.uk/index.php?topic=9543.msg67390#msg67390

I can't say which one you settled on as you never said

[BkS]

I do, and I never replied because it somehow managed to magically fix itself. This is the reason I resorted to this thread. I did use that search bar before I made it.

[Mark Greaves (PCNetSpec)]

Does the mic not work at all, or does it give static (white noise) ?


I know these are for a different Acer than yours (Acer Aspire 6920 - LF1) but I'm posting the links for future reference:
http://www.linlap.com/wiki/acer+aspire+6930
and
http://www.linlap.com/wiki/acer+aspire+6935g
and

[BkS]

Built in mic gives white noise, my headphones mic doesn't work at all.

EDIT: I've checked "Rec." in all the capture boxes :/

[Mark Greaves (PCNetSpec)]

Run this:

Code: [Select]

dmesg > ~/dmesg.txt

then attach the dmesg.txt file (in your Home directory) to your next post.


Question .. did it fix itself last time after clearing the DMI pool in the BIOS ?

[BkS]

Nope it didn't. It suddenly just worked one day after I switched to a profile. :/

[Mark Greaves (PCNetSpec)]

Have you tried installing the proprietary Realtek HD Audio Codecs .. which seem to have solved the issue for people with other Acer models ?

You can get them from here:
ftp://WebUser:wK9xBuD5@95.130.192.218/pc/audio/LinuxPkg_5.17rc1.tar.bz2
or the bottom of this page
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false

[BkS]

Would it be possibly to give some instructions on how to install?

From what I've learned I need to extract it to my home directory, then run:

Code: [Select]

cd ~/realtek-linux-audiopack-5.17

Code: [Select]

sudo ./install

Correct?

[Mark Greaves (PCNetSpec)]

Yup .. that's what the Readme.txt says .. so give it a shot.

If you haven't already, it would be best to install linux-headers-generic and build-essential first:

Code: [Select]

sudo apt-get install linux-headers-generic build-essential

[BkS]

Nope didn't fix it. It's also made the white noise on the built-in mic disappear. :-/

[Mark Greaves (PCNetSpec)]

Damn .. finding any info on the Acer Aspire 6920-LF1 is impossible .. is it known by any other name ?

What's the output from

Code: [Select]

arecord -l

and

Code: [Select]

aplay -l

and

Code: [Select]

lspci -v | grep -A7 -i "audio"

and

Code: [Select]

cat /proc/asound/card0/codec* | grep Codec

See if either of these help ..

sudo gedit /etc/modprobe.d/alsa-base.conf

try adding a new line at the bottom that reads:

options snd-hda-intel model=acer

options snd-hda-intel position_fix=1

or

options snd-hda-intel position_fix=2

and REBOOT to test.

[BkS]

Damn .. finding any info on the Acer Aspire 6920-LF1 is impossible .. is it known by any other name ?

Nope, not that I know of. Always been Acer Aspire 6920. LF1 is just the model number.

What's the output from

arecord -l

I'll try out the other suggestions in a second. Also noticed that my "bass tube" doesn't work either.

[Mark Greaves (PCNetSpec)]

I've come across info on 6920 and 6920g but I'm fairly sure we tried those fixes last time and the LF1 seemed to be a different model as a) the fixes didn't work, and b) your system was reporting different hardware to those.

I could be wrong .. that's just how I remember it.

I'll do some more searching tomorrow.

What were you running before PeppermintOS .. Oneiric ? .. so I can check on the ALSA versions.

And did everything work properly in that ?

From what I can work out, I've got the "G" model. So perhaps that'll help a bit. I was on Natty before and everything worked fine.
