[Bluez-users] hidd connection to mouse interferes with headset

[Bluez-users] hidd connection to mouse interferes with headset

[David Abrahams]

I am using a bluetooth mouse (logitech) and headset (plantronics) with
Ubuntu Feisty.

Without connecting the mouse, I can use the headset with Skype and get
reasonably good sound quality.

However, if I connect to my BT mouse with

  sudo hidd --connect <btaddr>

and try to use Skype again, I get horrible distortion, from "choppy
sound" to "white noise"

If I then

  sudo killall /usr/bin/hidd

sound in Skype goes back to normal.

Actually I have

  HIDD_ENABLED=1
  HIDD_OPTIONS="--connect 00:07:61:35:FE:A9 --master --server"

in my /etc/default/bluetooth, so all I need to do is turn my mouse
*on* to get this effect.

Does anyone have an idea how to cure (or even debug) this problem?

TIA,

Dave

if you have "master" in hcid.conf's lm setting and you take "rswitch"
and "sniff" out of the lp setting, you are forcing the pc to be master
and to hopefully behave better with audio. restart hcid.

I'll try these things; thanks.

What am I losing by making these changes (or, why are the settings
you suggest not the defaults)?

Brad,

these settings worked almost perfectly.  It's worth noting that the
mouse is somewhat less responsive when audio is going out to the
headset.  However, it's certainly tolerable, and not nearly as bad as
the "slushy mouse" effect I've experienced in the past.  Thank you!

[If you have a moment, I'd still like to know what those changes
actually did and why they're not the defaults]
