[Bluez-devel] Bluetooth ALSA: a2play plays MP3s too fast

[Adrian Glaubitz <glaubitz@physik.fu-berlin.de>]

Hi fellows,

after figuring out, how to set the passkey-agent for the HCI-daemon
I finally was able to connect my new SONY VGP-BRM1D bluetooth audio
headset with my Linux box and stream audio playback of mpg123 to
the headset with a2play. Here's what I did in short:

1. find headset with "hcitool scan"
2. set passkey for headset with "passkey-agent 0000 <address>"
3. connect to headset with "btsco -v -r <address>"
4. stream audio with "mpg123 --au - file.mp3 | a2play <address>"

The sound quality is just find with 44,1kHz, Stereo. But the playback
of the MP3 is just a bit too fast (high pitched) and varies with
CPU-load, i.e. getting the computer busy makes the music slow down.

I tried the various options for a2play regarding the timing stuff
(-i, -n, -p), but none helped. I also changed the value for "TICKS"
in the a2play-source (a2play.c).


Here my specs:

Kernel: Linux 2.6.19-rc5 (also 2.6.17.9)
Computer: IBM Thinkpad 240X, PIII-500, 192MB RAM
BT-Dongle: Acer Bluetooth USB
Headset: SONY VGP-BRM1D (http://www.jp.sonystyle.com/Qnavi/Detail/VGP-BRM1D.html).

Best Regards,

Adrian Glaubitz
