Trying to get a plantronics 510s headset working with skype (among other 
things) and I'm tantalizingly close. Hopefully someone can help close 
the gap.

I go the headset working for input and output with headsetd and headset 
plug-in: aplay and arecord -D headset working A-OK - my .asoundrc 
attached. Then I tried aoss skype - it *almost* worked. I could hear OK 
thru the headset but my voice was weirdly distorted and unrecognizable. 
I decided to recompile off the CVS head and now nothing works I get
  ALSA lib pcm_sco.c:532:(_snd_pcm_sco_open) Unknown field max_periods

Probably I have some mish-mash of versions installed, it's too late at 
night.

So what I'd like to know to speed my quest tomorrow:
 * In CVS there are multiple headsetd and alsa-plugins under plugz, 
btsco and alsa-plugin-sco. Which is the right one?
 * Maybe the distortion indicates some transformation of sound formats 
is needed - any hints as to what it might be?
 * Is there a better way than aoss for skype? It only shows alsa 
hardware devices in it's menus, I haven't found a way to make it use a PCM.
 * Any other  tips on what might be going wrong, or better ways to 
approach this?

I'll be happy to post my solution to the list if that's useful.

Thanks,
Alan.

Yes, please. I had to get a cable headset in order to use skype. I could 
hear sound and record sound through the bt headset (logitech), but skype 
  would only get me a beep and nothing more.

aoss didn't work either, maybe I shoudl try it again...

Cheers,
	Gerhard

Trying to use a plantronics 510s with skype.

Update on my attempts, I've established the setup that almost works. By 
almost works I mean:
- aplay, arecord -D headset work, quality is fine for telephone use.
- aoss skype almost works: I can hear the test call clearly, I can 
record a message but when it is played back my voice is garbled beyond 
recognition.

My next step is to fiddle with pcm settings - I've seen .asoundrc 
scripts for skype and dmix that do conversions between 8 and 16 bit 
formats and other stuff I know nothing about (but am afraid I'm gonna 
learn). Here are the details of how I got this far:

== DETAILS: based on btsco/docs/build.html from CVS, slightly modified.

install libsbc:

Note: When asking for a password simply press Enter.

cvs -d:pserver:anonymous@sbc.cvs.sourceforge.net:/cvsroot/sbc login
cvs -d:pserver:anonymous@sbc.cvs.sourceforge.net:/cvsroot/sbc co sbc
cd sbc
./bootstrap
./configure --prefix=/usr
make
sudo make install

install bstco:

cvs 
-d:pserver:anonymous@bluetooth-alsa.cvs.sourceforge.net:/cvsroot/bluetooth-alsa 
login
cvs 
-d:pserver:anonymous@bluetooth-alsa.cvs.sourceforge.net:/cvsroot/bluetooth-alsa 
co btsco
cd btsco
./bootstrap
# Note I added CFLAGS in ./configure. Without them the plugin emits
# a torrent of debug messages that slow it down and ruin the sound quality.
# -NDEBUG is essential, -03 is just for good luck.
./configure --prefix=/usr --enable-alsaplugin CFLAGS="-NDEBUG -03"
make
sudo make install

** Using from skype
My .asoundrc is copied from btsco/alsa-plugins/asound.conf with the
headset address replaced by my own and the following addition for aoss:

# Use headset via aoss emulation for skype.

pcm.dsp0 {
   type plug
   slave.pcm "hw_headset"     
}

Full .asoundrc attached. Run skype as "aoss skype" (you need alsa-oss 
package installed.)


== NOTES

The instructions at http://bluetooth-alsa.sourceforge.net/build.html did 
*not* work for me. The plugz version of the plugin requires a different 
.asoundrc (based on plugz/asound.conf) but aplay -D headset gave me:

[aconway@scooter plugz]$ aplay -D headset /usr/share/sounds/startup3.wav
Playing WAVE '/usr/share/sounds/startup3.wav' : Signed 16 bit Little 
Endian, Rate 44100 Hz, Stereo
aplay: set_params:909: Channels count non available

Cheers,
Alan.

Re: [Bluez-users] Headsetd, skype and bluetooth headsets.

[Ma Begaj]

Did you or someone else solve this problem?

I have the same problem. I applied the latest kernel patch (v4.2) with
the latest vanilla kernel 2.6.21.

I have Jabra 250v, sound is ok with aplay and arecord, hearing in
skype is ok,  but my recorded voice (echo123) is "garbled beyond
recognition".

Thanks

M.
