--- Comment #23 from Hans Petter Selasky <hselasky at FreeBSD.org> ---
Forwarding message from Nathanial Sloss:

> This is possibile on some headphones/speakers bta2dpd has the -B switch so the
> user can set the max bitpool value.  Is there hci dump on freebsd as seeing
> the output of getConfiguration will confirm this.  Otherwize increasing
> DEFAULT_MAXBITPOOL from 80 to say 160 in sbc_encode.h might work for his
> headphones but I am at a loss as to whether this will effect others.  The

Tony: Could you try to change the definition of DEFAULT_MAXBITPOOL?
