[Bluez-devel] Audio to headset

[Jérôme Stadelmann]

Hello everybody,

I'm actually working on a diploma project with bluetooth and audio. I =
have
an Anycom Bluetooth USB adapter and an Ericsson HBH-15 headset. I would =
use
first the hstest example in order to send some music to the headset but =
it
doesn't work. I only hear some noise but no music.

Is this command correct ? "hstest play music.mp3 xx:xx:xx:xx:xx:xx"

I have mpg123 and sox installed,
scoinfo return PSKEY_HOSTIO_MAP_SCO_PCM: 0x00,
voice setting is 0x0060.

The pin works and I receive back from the headset the AT commands =
(AT+VGS=3D11
and AT+CKPD=3D200) but I only hear some noise.

Could somebody please help me in this?

Jerome

why don't you try hsplay?

What kernel version are you using? Try one of my latest patches for 2.4.

Marcel

Hi Marcel,

I have used hsplay with the same result.
My kernel version is 2.4.21 from a SuSe distribution.
I'll then use your kernel patch.

Regards,

Jerome

this kernel don't work correct. Try at least 2.4.21-mh4 and I suggest
you to upgrade to 2.4.24-mh2.

Do you use an older kernel without Marcel's patches maybe?
I've also had problems with an older Mitsumi Bluetooth adaptor, but with it=
=20
the output sounds a little bit like the expected signal at least.
Do you just get random noise or does it correspond somehow to the music?

I don't have a headset to try, but I thought hstest works with uncompressed=
=20
audio data only. Or I just didn't notice.. I'd try a wave file (16 bit mono=
?)=20
instead.
