[Bluez-users] State of snd-bt-sco

[Bluez-users] State of snd-bt-sco

[Carlos Azevedo]

Greetings,

Is snd-bt-sco (from the CVS) currently working ? I can get btsco (the app) to 
connect to the headset 
(http://sourceforge.net/mailarchive/forum.php?thread_id=6030842&forum_id=1883)
and get the following :

Device is 1:0
Voice setting: 0x0060
RFCOMM channel 1 connected
recieved AT+CKPD=200
opened hwdep
connected SCO channel
Setting sco fd
Done setting sco fd
recieved AT+VGS=04
Sending up speaker change 4

but when I run aplay (aplay -D hw:1 prompt-copia1.wav) or arecord it exits 
with

Playing WAVE 'prompt-copia1.wav' : Signed 16 bit Little Endian, Rate 8000 Hz, 
Mono
aplay: pcm_write:1118: write error: Input/output error

I've sprinkled the kernel driver with dprintks but apparently there is no data 
going from the SCO socket to the ALSA driver.
By the way both in btsco and in the driver there's some structs and other 
variables declared inside the code (not at the top of the function). GCC 
2.95.x doesn't like it, so it would be nice if they were moved upstream.

I really need this stuff working, so please give me some pointers as I am 
wiling to hack the code (and hopefully able...)

I have not tested it since the module was made standalone. No one has 
reported using it with your plantronics m2500 headset. Do you have a 
different adapter (like a CSR-based usb) you could try it with by the way?

looks good

does it exit immediately or after a timeout?

if you're using gnome, be sure to "esdctl off" so you're not competing 
with esound.

i had to get everything just perfect with alsa before it would work. 
what does the also stuff in modules.conf look like? mine is:

options snd major=116 cards_limit=2 device_mode=0660 device_gid=29 
device_uid=0

alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

alias snd-card-0 snd_intel8x0
alias snd-card-1 snd_bt_sco
#alias snd-card-2 snd-share
#alias snd-card-3 snd-virmidi

alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1
alias sound-slot-2 snd-card-2
alias sound-slot-3 snd-card-3

also i found my "alsasound" script under debian was not set up to start 
at boot.

for me it is working. What is the output of "hciconfig -a"? What kernel
are you running and what Linux distribution do you use? Do you checked
with hcidump what packets are sent?

What about sending in a patch?

this is the one that still has problems. What kernel are you using? If
the latest 2.6.10-rc2 or 2.6.9-mh4 are not working then someone needs to
send me one of these so I can take a closer look at the problem. The
dongle 0a5c:200a from Broadcom is working fine.

Regards

Marcel
