Hi,

I've got the MS IntelliMouse Explorer for Bluetooth, and a pair of Orange
Bluetooth speakers
(http://www.acoustic-energy.co.uk/News_and_reviews/orangebluetooth.asp).
I'm using Feisty Fawn and have configured bluetooth-alsa to stream all
sounds to the bluetooth speakers (via .asounrc in pcm.!default) which works
well enough if it's the only bluetooth device I'm using.

The only issue is, whenever I connect and move the mouse (using hidd) while
I'm streaming music using a2dpd, the music starts cutting out and jumping
until I stop moving the mouse. My first thought was that the bluetooth
device reached a bandwidth limit. However, a thought occurred to me- since
the mouse is sending to the bluetooth device, but the speakers are receiving
from the device- is there not a separate send/receive bandwidth?

One thing I have tried is disabling the bluetooth sniff mode by echoing 0 to
/sys/class/bluetooth/hci0/idle_timeout, which I think may be providing a
slight improvement on things (altho it's hard to tell). Am I expecting too
much from my bluetooth transceiver? Anyone have any ideas how I can improve
the performance of these two devices working together?

Regards,
Alex
