Hi,
I am using android [bluez-3.36] and using a2dp over it. I observe that I get a lot of audio gaps, when I connect to headset "Jabra BT620s".
However when I connect to "Motorola HT820", everything seems fine, audio streaming is good.
I have the hcidump, when the Jabra was connected, and it kind of reads the same in terms of frequency, Stereo, block size as when connected to Motorola headset
What could be the problem ? Any inputs would help.
Thanks,
Pavan

The audio metering code in liba2dp.c

Hey Nick,
I did post this on the android-group as well, I mentioned I get a "write blocked for ** msecs" when audio gap occurs.
Also, I tested Jabra with ubuntu's 3.16 bluez, it sounds funny [something to do with frequency, I suppose..],
but no audio gap, basically same output as in Motorola head-set.
Also please elaborate on what part of Android plug-in do you suspect ? I would want to take a look into it.
regards,
Pavan

While I suspect this issue is specific to the Android a2dp audio
plugin, I would also be interested in hearing if the pulseaudio or
alsa plugin's have issues with Jabra headsets as Pavan describes.
