hello
I have just installed bluez-4.30 on my machine running linux 2.6.28-rc6 and have found that aplay no longer works every time. As you can see it worked once in five attempts.

Once I got a bit of music then a different message

Sometimes it works until the end of the song. I have a Jabra JX10 headset and a Belkin F8T017 Bluetooth adapter.

This is all part of my attempts to get bluez (>4.19) and twinkle http://twinklephone.com/ to talk to each other!
