No sound from usb on Motorola C350 cellphone

Hi list participants,

I am using cellphones connected to soundcards as cheap gsm gateways
(more complex than that, actually. You can see the whole GPL project
at www.celliax.org).

Maybe there is a way to not using soundcards, that would be *so* much
better: I found that Motorola c350 phones after receiving an AT+MODE=8
command via USB, make available an usb sound device.

That would be wonderful (less cables, more robustness, etc). Problem
is: the usb sound device do not plays or captures samples.

I suspect that the usb audio has to be activated, maybe by an AT or a
P2K command.

Or that a quirk has to be added to the alsa driver (snd_usb_audio).

Do you know anything about (maybe the quirk to be added to ALSA driver...)?

Do you have any hint?

I'm available to do all the research-testing-debugging that may be useful.

What happens is as follow:
1) attach the c350 to usb
2) is recognized as acm0
3) send at+mode=8 to c350 (via minicom, for eg)
4) it changes its usbid, disconnect from usb, reconnect, is recognized
as acm1, makes available a sound device
5) at commands work on the new acm1
6) trying to use the audio device directly (eg aplay -Dhw:1) do not
give errors on play (but no sound is head on the phone), gives error
pcm_read 1349 on record (eg arecord -Dhw:1)
7) trying to use the audiodevice through alsalib does not gives errors
at all (eg -Dplughw:1) but does not caputeres samples, and no sound is
heard on the phone


I'm attaching:

lusb_without -> result of lusb -vv with no device attached

lsusb_with_ACM0 -> result of lusb -vv with c350 just attached,
recognized as acm modem

lsusb_with_ACM1 -> result of lusb -vv with c350 after sending
at+mode=8 to him, he has disconnected and was recognized again, this
time as ACM1, with a lot of additional usb interfaces

dmesg-acm0 -> result of dmesg after first c350 attachment

dmesg-acm1 -> result of dmesg after at+mode=8 was sent to the c350

aplay-l -> result of aplay -l showing the c350 as an alsa device

stream0_pstop_cstop -> result of cat /proc/asound/C350/stream0 while not active

stream0_pstop_crun -> result of cat /proc/asound/C350/stream0 while
arecord -vv -Dplughw:1 -fS16_LE ciapa.raw (if using -Dhw:1 it fails
with error: "pcm_read:1349: read error: Input/output error"). arecord
does not gives errors, but do not write samples

stream0_prun_crun -> result of cat /proc/asound/C350/stream0 while
aplay and arecord -vv -Dplughw:1 -fS16_LE ciapa.raw (if using -Dhw:1
arecord fails with error: "pcm_read:1349: read error: Input/output
error", aplay works but no audio) arecord does not gives errors, but
do not write samples

aplay_play -> results of aplay

arecord_rec -> results of arecord

Thank you all in advance,

Giovanni Maruzzelli

No sound from usb on Motorola C350 cellphone

[Giovanni Maruzzelli]

[-- Attachment #1: Type: text/plain, Size: 2786 bytes --]

Hi list participants,

I am using cellphones connected to soundcards as cheap gsm gateways
(more complex than that, actually. You can see the whole GPL project
at www.celliax.org).

Maybe there is a way to not using soundcards, that would be *so* much
better: I found that Motorola c350 phones after receiving an AT+MODE=8
command via USB, make available an usb sound device.

That would be wonderful (less cables, more robustness, etc). Problem
is: the usb sound device do not plays or captures samples.

I suspect that the usb audio has to be activated, maybe by an AT or a
P2K command.

Or that a quirk has to be added to the alsa driver (snd_usb_audio).

Do you know anything about (maybe the quirk to be added to ALSA driver...)?

Do you have any hint?

I'm available to do all the research-testing-debugging that may be useful.

What happens is as follow:
1) attach the c350 to usb
2) is recognized as acm0
3) send at+mode=8 to c350 (via minicom, for eg)
4) it changes its usbid, disconnect from usb, reconnect, is recognized
as acm1, makes available a sound device
5) at commands work on the new acm1
6) trying to use the audio device directly (eg aplay -Dhw:1) do not
give errors on play (but no sound is head on the phone), gives error
pcm_read 1349 on record (eg arecord -Dhw:1)
7) trying to use the audiodevice through alsalib does not gives errors
at all (eg -Dplughw:1) but does not caputeres samples, and no sound is
heard on the phone


In the tgz archive attached you can find the following files:

lusb_without -> result of lusb -vv with no device attached

lsusb_with_ACM0 -> result of lusb -vv with c350 just attached,
recognized as acm modem

lsusb_with_ACM1 -> result of lusb -vv with c350 after sending
at+mode=8 to him, he has disconnected and was recognized again, this
time as ACM1, with a lot of additional usb interfaces

dmesg-acm0 -> result of dmesg after first c350 attachment

dmesg-acm1 -> result of dmesg after at+mode=8 was sent to the c350

aplay-l -> result of aplay -l showing the c350 as an alsa device

stream0_pstop_cstop -> result of cat /proc/asound/C350/stream0 while not active

stream0_pstop_crun -> result of cat /proc/asound/C350/stream0 while
arecord -vv -Dplughw:1 -fS16_LE ciapa.raw (if using -Dhw:1 it fails
with error: "pcm_read:1349: read error: Input/output error"). arecord
does not gives errors, but do not write samples

stream0_prun_crun -> result of cat /proc/asound/C350/stream0 while
aplay and arecord -vv -Dplughw:1 -fS16_LE ciapa.raw (if using -Dhw:1
arecord fails with error: "pcm_read:1349: read error: Input/output
error", aplay works but no audio) arecord does not gives errors, but
do not write samples

aplay_play -> results of aplay

arecord_rec -> results of arecord

Thank you all in advance,

Giovanni Maruzzelli

Seems that there is a problem in sending compressed attachments (and
non compressed is over the max limit size for list).

So, you can get the attachment with all the files at:
http://www.celliax.org/c350_usb_sound.tgz

Sorry for the mess,

Giovanni

Confirmed with my Motorola C350 cellphone. It appears to accept S16_LE, MU_LAW 
and A_LAW formats, 8 kHz sample rate, but actually records no data and plays no 
sounds (even if a cal is in progress).

One question: what playback and recording functionality is available on this 
cellphone under Windows?

With an old copy of motorola driver, the usb sound device was
recognized by windows XP, with mixer elements only for the playback. I
was  not able to record from it, playing give no errors, but no sound
either

With the last copy of driver from motorola developer devsite, on XP a
whole new "Motorola Device" is created, with the audio interface
listed on it in the usb control panel, but no audio device is
available for normal usage.

Needs more info, tests?

If you can make the audio functionality work under Windows 2000 or XP with the 
new (non-standard) driver, snoopy logs will be interesting. Snoopy is available 
from http://www.wingmanteam.com/usbsnoopy/ or (different version) 
http://sourceforge.net/projects/usbsnoop/

Hi All;

I think this is a totally fascinating thing and i hope it will be
possible to make it work.....

onto the specifics

i am not staring at the USB code right now (it's on a different box),
but i would think that one of the first things that you might need to
uncover is the USB device string. It may be offered up as part of the
device probe when it's attached (check in dmesg) or you may find it in
a registry or .inf file on the windows file system after you install
the drivers.

if it's a class compliant device, then it may just work once alsa get's
taught about it (dont hold me to that, i am not looking at code)

however, as one of you alluded to, there may be an AT command that
needs to get tickled to turn it on.

the other annoying thing to consider is that it may actually be probe
and connected, but you havent yet figured out how to turn up the
volume :-( (yes, that happens)

i'll be really curious about this, so please continue to share with
the list....

tnx!

[Giovanni Maruzzelli]

Johnu,

device string, and all the "usual" kind of detailed informations are
in the files contained by the compressed archive you can download at:
http://www.celliax.org/c350_usb_sound.tgz (lsusb -vv before and after,
stream0, etc etc).

maybe there is need for a quirk in snd_usb_audio ?

the problem is that the device appear to works, but do not captures or
plays samples.

Re: No sound from usb on Motorola C350 cellphone

[Jesse Burt]

Giovanni,

I agree with John, this sounds very interesting; I have been looking to
do something at least remotely related to this, but standalone (though
perhaps I've misunderstood the purpose of your software completely).
I've been searching for a way to use a host PC as a
handsfree/speakerphone for my v3/v3x via bluetooth. The closest I've
come is the software at:
http://wall4.soft.uni-linz.ac.at/_wiki/tiki-index.php?page=ProjectBluezHandsfree

...but I only once got it to partly work with my V3 (very little audio,
and all broken up) and no audio at all with my V3x.
It seems the links to the tarballs are dead though so if anyone wants
them I think I can find them somewhere on my computer.

I have tried sending the 'AT+MODE=8' command to my phone and it indeed
does trigger a change in the USB state: it disconnects and attempts to
reconnect, but fails.

Also I don't mean to flood the list with something that might be
considered offtopic so unless someone feels any of what I've said is
relevant this will be my first and last post.

Cheers,
Jesse Burt
