[Bug 405294] Re: A2DP Bluetooth audio skips terribly ["Skipping NNN us (= MMM bytes) in audio stream"]

[PeterPall]

Since the history of Bug 1746164 isn't visible here I'm adding the short
form here, too:

By default BT audio works fine on Ubuntu - if there is no WiFi active:
Both work on the same frequency range, 2 WiFi channel is about 20
Bluetooth Channels wide and every time a WiFi package is sent bluetooth
risks a packet loss.

We should ship things in a way that they work out-of-the-box => I am all
for providing this file with Ubuntu, possibly with Bluez.

In the case of my laptop btcoex_enable=1 would already do the trick.

Technical background:
 - https://wireless.wiki.kernel.org/en/users/drivers/ath9k/btcoex
 - https://wiki.freebsd.org/dev/ath_hal(4)/AntennaDiversity

Until the kernel default is updated Creating a file named
/etc/modprobe.d/bluetooth-audio.conf with the following content:

options ath9k btcoex_enable=1 bt_ant_diversity=1

should do the trick.
