Thanks for reply. can a2play run on OSS too?

I am not very sure of a2play's design now.

I ported BlueZ on an embeded ARM7 running at 80 MHz.

I also try a2recv on embeded board with sound chip using OSS

driver. Printout looks ok, but can't hear anything:

---------------------------------------------------------------------

> ./a2recv

Connected [imtu 672, omtu 672, flush_to 65535]
Connected
Sent Stream End Point Discovery Response

Sent the get capabilities responseChannels=2, speed=44100channel_mode = 2 alloca tion_method = 2 subbands = 1 block_length = 1 min_bitpool = 2 max_bitpool = 250

Sent a Set configurations response

Received an open stream command

Sent open stream confirm

Connected [imtu 672, omtu 672, flush_to 65535]
ConnectedGot stream fd

Sent start stream confirm
------------------------------------------------------------------------------

The above logs are OK. It means that the A2DP source is streaming to your target device.

The only reason that you do not hear anything can be an endian problem. Maybe the endian type in which the SBC is decoded is different from the one that your device supports.

Don't you even hear any noise?

By the way are you using the latest version of a2recv?

Is CPU (ARM7 @80MHz) powerful enough to run a2recv ?

I think it should be powerful enough.

Mayank
