 Hi,
 
 In the message[1] you say that bluetooth audio on the gta01 will
 never work, even with that bluetooth alsa state.
 
 Could you please explain what exactly did you mean and what is the
 actual problem? Were you talking about A2DP or SCO? If SCO, was it SCO
 over PCM or HCI? If A2DP, what is the difference between gta01 and
 gta02 in this regard, should it work correctly on gta02 in your
 opinion?

Jan Lübbe has recently made a phone call with a bluetooth headset on
GTA02 and I got A2DP working (though mono) on my GTA01 a while back.
A2DP should just work since you are not going through the Wolfson chip
in any way.
Phone calls via headset is another story and I can't answer that for
GTA01, but I think we didn't change anything in that area from GTA01 to
GTA02.

Daniel Willmann

Yes, to the best of my knowledge, there were no changes wrt SCO PCM
between GTA01 and GTA02. The same with USB HCI interface. That's why i
was very surprised to see that message from Lorn.

Still it looks like asoc driver for GTA01 will need to be backported
from GTA02, but it's a matter of software, so it can be made to work.

It is a good move towards that indeed, thanks for that! :) Still i'm
afraid some other strange stuff left in the GTA01 driver like moko
mode etc. In fact, i see no reason for the drivers to differ
much. Another problem is that we still don't have a good way to
generate statefiles, which is needed for any sane audio work
(especially after some driver changes) :)
