I have a similar problem. I'm using Creative CB2530 headphones, and they work
absolutely fine for around 2-3 minutes and then audio stops working (does seem
slightly random, but always within 2-3 minutes.) This is with an audio sink
setup, my headphones connect automatically and work with all applications.

I saw your tips above about changing the settings in hcid.conf, which i have
done, and it has made no difference.

I'm seeing this in the syslog:

15:27:17  audio[5742]: stream state changed: OPEN -> STREAMING (starts working)
Then suddenly it stops:
15:30:16  audio[5742]: session_cb
15:30:16  audio[5742]: Received CLOSE_CMD
15:30:16  audio[5742]: SBC Source: Close_Ind
15:30:16  audio[5742]: stream state changed: STREAMING -> CLOSING
15:30:16  audio[5742]: stream state changed: CLOSING -> IDLE
15:30:16  audio[5742]: avdtp_unref(0x806b598): ref=2
15:30:16  audio[5742]: SBC Source SEP 0x80694b8 unlocked
15:30:16  audio[5742]: avdtp_unref(0x806b598): ref=1
15:30:16  audio[5742]: session_cb
15:30:16  audio[5742]: Disconnected from 00:12:0E:09:CF:9E

If i run ~$ hcitool con before it fails:
Connections:
        < ACL 00:12:0E:09:CF:9E handle 41 state 1 lm MASTER
