Upgrading Skype 2.0 to Skype 2.2 beta on Debian
GNU / Linux - Skype Mic hell
Though, I'm
GNU / Linux user for many years now. I have to
say, everything is not so perfect as many people present it.
Configuring even simple things related to multimedia on Linux is
often a complete nightmare.
An example, today I've decided to upgrade my
32 bit Skype
version 2.0 beta for Linux to
64 bit Skype 2.2 beta
.
The reason I was motivated to upgrade skype was basicly 2.
a) My Skype run through 32 bit binary emulation with
/usr/bin/linux32
b) I had issues with my skype if someone give me a
Skype
Call, while I have a flash video or some other stream in
Browser (let's say Youtube).
Actually being unable to receive a skype call or initiate one while
I have some kind of music running in the background or just some
kind of Youtube video paused was really annoying. Hence until now,
everytime I wanted to speak over skype I had to close all Browser
windows or tabs that are using my sound card and then restart my
Skype program ....
Just imagine how ridiculous is that especially for a modern
Multimedia supporting OS as Linux is. Of course the problems, I've
experienced wasn't directly a problem of Linux. The problems are
caused by the fact I have to use the not well working proprietary
software version of Skype on my Debian GNU / Linux.
I would love to actually boycott Skype as
RMS recommends,
but unfortunately until now I can't, since many of my friends as
well as employers use Skype to connect with me on daily
basis.
So in a way I had to migrate to newer version of skype in order to
make my Linux experience a bit more desktop like ...
Back to the
my skype 2.0 to 2.2. beta upgrade story, the
overall Skype upgrade procedure was easy and went smootlhy, setting
correct capturing later on however was a crazy task ....
Here is the step by step to follow to make my upgraded skype and
internal notebook mic play nice together:
1. Download 64 bit Skype for Debian from
skype.com
For the sake of preservation in case it disappears in future, I've
made a
mirror
of skype for debian you can download here
My upgrade example below uses directly the 64 bit Skype 2.2beta
binary mirror:
Here are the cmds once can issue if he has to upgrade to 2.2beta
straight using my mirrored skype:
debian:~# wget
http://pc-freak.net/files/skype-debian_2.2.0.35-1_amd64.deb
...
2. Remove the old version of skype
In my case I have made my previous skype installation using
.tar.bz2 archive and not a debian package, however for some
testing I also had a version of skype 2.0beta installed as a deb so
for the sake of clarity I removed the existing skype deb
install:
debian:~# dpkg -r skype
...
3. Install the skype-debian_2.2.0.35-1_amd64.deb downloaded
deb
debian:~# dpkg -i skype-debian_2.2.0.35-1_amd64.deb
...
After installing skype, I installed
pavucontrol -
A
volume control for the PulseAudio sound server
4. Install pavucontrol
debian:~# apt-get install pavucontrol
Pavucontrol has plenty of sound configurations and enables
the user to change many additional settings which cannot be tuned
in
alsamixer
pavucontrol was necessery to play with until I managed to
make my microphone able to record.
5. Build and install latest Debian (Testing) distribution alsa
driver
debian:~# aptitude install module-assistant
debian:~# m-a prepare
debian:~# aptitude -t testing install alsa-source
debian:~# m-a build alsa
debian:~# m-a install alsa
debian:~# rmmod snd_hda_intel snd_pcm snd_timer snd soundcore
snd_page_alloc
debian:~# modprobe snd_hda_intel
debian:~# echo 'options snd-hda-intel model=auto' >>
/etc/modprobe.d/alsa-base.conf
In my case removing the sound drivers and loading them once again
did not worked, so I had to
reboot my system before the new
compiled alsa sound modules gets loaded ...
The last line
echo 'options snd-hda-intel model=auto' ...
was necessery for my Thinkpard r61 Intel audio to work out. For
some clarity my exact sb model is:
debian:~$ lspci |grep -i audio
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD
Audio Controller (rev 03)
For other notebooks with different sound drivers
echo 'options
snd-hda-intel model=auto' ... should be omitted.
6. Tune microphone and sound settings in alsamixer
debian:~$ alsamixer
Right after launching
alsamixer I had to
press F6: Select
Sound Card and choose my sound card
(0 HDA Intel).
Following my choose I unmuted all the microphones and enabled
Microphone Boost as well as did some adjustments to the MIC volume
level.
Setting proper MIC Volume levels is absolutely necessery, otherwise
there is a constant noise getting out of the speakers ...
7. Use aumix to set some other sound settings
For some unclear reasons, besides
alsamixer , I often had to
fix stuff in
aumix . Honestly I don't understand where
exactly aumix fits in the picture with Alsa and my loaded alsa
sound blaster module?? If someone can explain I'll be
thankful.
Launch
aumix to further adjust some sound settings ...
debian:~$ aumix
In above screenshot you see, my current aumix settings which works
okay with mic and audio output.
8. Test Microphone the mic is capturing sounds
correctly
For the sake of test if my sound settings set in
pavucontrol
enables the
internal mic to capture sound I used two
programs:
1. gnome-sound-recorder
2. arecord
gnome-sound-recorder
gnome-sound-recorder is probably used by most GNOME users, though
I'm sure Linux noviced did not play with it yet.
arecord is just a simple console based app to capture sound
from the microphone. To test if the microphone works I captured a
chunk of sounds with cmd:
debian:~$ arecord
Recording WAVE 'cow.wav' : Unsigned 8 bit, Rate 8000 Hz,
Mono
Later on I played the file with
aplay (part of alsa-utils
package in Debian), to check if I'll hear if mic succesfully
captured my voice, e.g.:
debian:~$ play cow.wav
cow.wav:
File Size: 22.0k Bit Rate: 64.1k
Encoding: Unsigned PCM
Channels: 1 @ 8-bit
Samplerate: 8000Hz
Replaygain: off
Duration: 00:00:02.75
In:100% 00:00:02.75 [00:00:00.00] Out:22.0k [-=====|=====-]
Clip:0
Done.
Finally I launched the new installed version of skype and tested
Skype Calls (Mic capturing), with
Skype Echo / Sound Test
Service
I'll be glad to hear
if this small article, helped anybody to
fix any skype Linux related issues ?. I would be happy to hear
also from people who had similar issues with a different fixes for
skype on Linux.
Its also interesting to hear from Ubuntu and other distributions
users if following this tutorial had somehow helped in resolving
issues with Skype mic.
