Hi, All:
If you use Linphone on Arch, beware. The latest release built 31 August
introduced what for me is a showstopper bug. I'm referring to
Linphone-3.10.2-1.
It is no longer possible to specify which audio device Linphone should
use. Here's the relevant bit of configuration from my older
.linphonerc:
[sound]
ringer_dev_id=ALSA: Sennheiser USB Headset
playback_dev_id=ALSA: Sennheiser USB Headset
capture_dev_id=ALSA: Sennheiser USB Headset
This device is still present and working on the system:
aplay -l |grep card
card 0: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog]
card 0: PCH [HDA Intel PCH], device 1: ALC892 Digital [ALC892 Digital]
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
card 1: Device [C-Media USB Audio Device], device 0: USB Audio [USB Audio]
card 2: Headset [Sennheiser USB Headset], device 0: USB Audio [USB Audio]
card 3: AV710 [Chaintech AV-710], device 0: ICE1724 [ICE1724]
card 3: AV710 [Chaintech AV-710], device 1: ICE1724 IEC958 [ICE1724 IEC958]
card 3: AV710 [Chaintech AV-710], device 2: ICE1724 Surrounds [ICE1724 Surround PCM]
card 4: DSP [Hammerfall DSP], device 0: RME Hammerfall DSP + Multiface [RME Hammerfall DSP + Multiface]
However, linphone no longer sees it:
soundcard list
0: PulseAudio: Built-in Audio
1: ALSA: default device
linphonec>
So, I'm investigating workarounds because I depend on linphone for my
standards work--lots of teleconferences. Meanwhile, I do believe it's my
duty to report this development as I've now seen exactly this same
problem on two separate Arch machines.
Caveat emptor.

Hi Janina,
I think I might have a solution for you.
The only reason this will work is that you are using the headset for all
three functions: ringer, playback, and capture. If you needed something
fancier, this falls flat.
You can set a specific default card for a given application using the
ALSA_CARD environment variable.
For instance,
ALSA_CARD=Headset espeak 'Hello there.'
should cause espeak to speak the string through your headset.
So try setting ALSA_CARD when starting linphone.
Now there's another problem in that Linphone seems to want to use
pulseaudio for the default sound output. Can't help you with that one.
Maybe the config file would at least let you specify alsa rather than
pulse?

It was a great suggestion, Chris. Unfortunately, it seems there's yet
another bug in how alsa handles usb devices.
I have 2 usb devices. No matter how I specify things, the card that gets
invoked is the first of those two.
Now, if I were really clever, I suppose I'd know how to write udev rules
to insure that the Sennheiser gets a lower card ID than the C-Media
device. This really should be an exact science, but my experience says
it's anything but.
Sigh.

I think you can use names instead of numbers, maybe a different
variable in your asoundrc.

Tried that. No joy.
Actually, names are less reliable than the hw:X (or plughw:X)
designations.
Note this is a problem when there's more than one USB sound device. I've
not seen the problem apart from USB sound.

Oh interesting. So it looks like there's a name clash.
Last time I dealt with multiple USB audio devices, they had unique
human-friendly IDs by default. My Logitech USB headset was called
Headset, and my FM transmitter was called RocketFM.
Apparently I was just lucky.
Not sure how much you know about alsa, so I'll also mention that
you can see the human friendly IDs by looking for the symlinks in
/proc/asound. They're also listed in the output of aplay -l, but it's
sort of non-intuitive what they are.

Well if you send me the output of lsusb, I can probably write some udev rules
for you. Or alternatively have a look at http://alsa.opensrc.org/Udev for a
starting point.

You've put me on the trail of docs I've looked for and failed to find
forever.
I'm now looking at:
http://alsa.opensrc.org/MultipleCards
If I'm reading this correctly, I should be able to get the results I
need by specifying a vendor and product id to order my two usb cards
like I want them ordered.
Very cool. Hope it works!

Haha! Chris Brannon, you rock! Mission accomplished
I now have in /etc/modprobe.d/alsa.conf the USB sound card device
ordering that makes the trick you suggested work like a charm:
ALSA_CARD=Headset linphonec; linphonec
brings up the SIP phone and works as expected. I think this will
seriously do until the real thing comes along! <satisfied grin>
Thanks again, Chris!

Aha. I had forgotten about that.
Anyway, here are the udev rules to name your cards. Unless I messed up
somewhere, these should give you the names Sennheiser and CMedia.
It's overly commented, partly for my benefit, because I don't
write udev rules too often.
Here's a link. I think mailman scrubs attachments, and I don't want it
to be mangled by pasting it inline.

Hi, Chris:
I will give your rules a spin and report back--but not today, just in
case there's a problem. I have calls today, but I'm clear of them at
day's end.
Thanks also for not pasting them inline. I had a profound experience of
executing a script that I recieved from a very brilliant engineer
colleague once.
As luck would have it, a mailman reformat of a line break ended up
executing:
rm -rf $HOME
I kid you not. This actually happened to me shortly after I lefft AFB. I
took it as spiritual encouragement to put the past behind me and not
worry about it anymore! It's funny now. At the time it was rather
devestating.
So, more news over the weekend, and thank you again for your stellar
assistance.
