Hi,
I am having trouble with alsa audio and bluez. It seems to be a bluez problem because it works correctly with a USB transport, but not with UART. Scenario is as follows:
1. Paired to Bluetooth headset (CSR BC6rom based if that matters)
2. Record 10 seconds of audio with arecord -d 10 -r 8000 -f S16_LE -D sco myaudio.wav
With a UART interface (via hciattach) arecord runs for 20+ seconds, but the wav file contains only 10 seconds of audio. That 10 seconds of audio is actually the 20+ seconds compressed (sped up).
With a USB interface (USB dongle) arecord runs for 10 seconds and the audio is as expected.
It seems that it has to be some sort of sample rate problem, but I am not sure where to look next. I am currently looking in pcm_bluetooth.c, but not really familiar with the inner workings of bluez. I have included the output of the alsa-info which has more detailed information, but the summary follows:
Kernel ubuntu 2.6.28.9
Bluez 4.50
Alsa 1.0.21
Any help is greatly appreciated,
