[Bluez-devel] "unable to install hw params" to bluetooth (SCO) headset (was: btusb+sco failing to play sound through Jabra BT500v headset)

Hello

I have read Martin's messages concerning his Jabra BT500v bluetooth headset.

I have similar problems with my Jabra JX10 headset. I have installed
bluez-4.4. When I run aplay with a 2.6.26 kernel, aplay works. When I
run aplay with linux 2.6.27-rc5 I can hear a hiss when my PC connects to
the headset but no music.

I have written a long bug report on
http://bugzilla.kernel.org/show_bug.cgi?id=11514 with the output of
hcidump -X -V and the messages from bluetoothd. Could someone have a
look and give me a hint about what I might be doing wrong? Has anyone
had any luck with Jabra headsets and 2.6.27-rc5 or should I buy a
different brand of headset? Marcel Holtmann said that "It simply works
for me." What headsets have you tested?

aplay always says "Unable to install hw params" after bluetoothd says
"connect(): Connection timed out (110)" but hcidump shows lots of SCO
packets being sent to the headset.

thanks
Stuart
