bluetooth audio fails

bluetooth audio fails

[Ramagudi Naziir]

Hi all,

Can anyone pls help me debug this:

# aplay -D bluetooth /startup.wav
ALSA lib audio/pcm_bluetooth.c:1607:(audioservice_expect)
BT_GET_CAPABILITIES failed : Input/output error(5)
aplay: main:608: audio open error: Input/output error

I'm running the latest bluez git sources with a 9xxPlantronics HFP headset.
I tried both "auto" and "voice" in .asoundrc:

pcm.bluetooth {
        type bluetooth
        device mybdaddr
        profile “voice”
}


Any idea what this could be and how to debug/fix it ?

thank you
naziirr

I have just tried that also with a Motorola H700 headset,
and got exact same error message.

(I also tried bluez 4.56 and got same error)

please help me to debug this.

thank you,
naziirr

I have just tried that with bluez 3.36 and it works!

So - should I downgrade to bluez 3.36 ?

Can you just tell me how you would debug this ?

Hi Mark,

thank you - good tip !

These are the logs I see when I try to run the aplay command:

bluetoothd[1260]: Accepted new client connection on unix socket (fd=23)
bluetoothd[1260]: Audio API: BT_REQUEST <- BT_GET_CAPABILITIES
bluetoothd[1260]: sending error Input/output error(5)
bluetoothd[1260]: Audio API: BT_ERROR -> BT_GET_CAPABILITIES
bluetoothd[1260]: Unix client disconnected (fd=23)
bluetoothd[1260]: client_free(0x2a09f318)

change applied (same results, though).

can't - I have no screen :)

I use the C agent for that:

# /test/agent 0000 00:14:13:00:25:93
Pincode request for device /org/bluez/1260/hci0/dev_00_14_13_00_25_93
Agent has been released

It seems successful, and indeed the device seems to be paired.
What strikes me as odd is that I can't see any link-key info in
/var/lib/bluetooth.
I only see there my laptop and no headset which I seem to pair with
successful (and I've tried already 3 different headsets, all yield the
same result).


Besides that, I see 2 errors in the logs.

1. while executing running bluetoothd, I see this line:
bluetoothd[1260]: Failed to open control socket: Protocol not supported (93)
Is this bad or can I ignore it ? what socket is it ? NETLINK ? what it
is used for ?

2. while adding (+up'ing) hci0, I see this line:
(bluetoothd:1260): GLib-CRITICAL **: g_key_file_get_boolean: assertion
`key_file != NULL' failed
...
bluetoothd[1260]: Adapter /org/bluez/1260/hci0 has been enabled
bluetoothd[1260]: Failed to access HAL

can you pls also tell me what are those errors and whether I should debug them ?

yes: bluez-git/test/agent.c

for some reason it is not being created. weird.

yes

it's a UART device. and it looks like it works pretty good - I got
rfcomm to work with my laptop (which means scan, connect, pair worked,
and I got a binded /dev/rfcomm0 that I could write to and read from
and see the laptop data).


Thank you!
