Bug Description

When I connect my Aquaris E4.5 to my car's handsfree device (Funkwerk Ego Flash) via Bluetooth I experience a skipping problem when playing sound files through A2DP.

Half a second for each second there is a pause. The rest of that half second seems to clear a buffer which results in "extra fast" audio.

To illustrate, listening to a podcast I would expect to hear something like "bla bla bla". However, what I do get to hear sounds more like "flapflapflap - pause - flapflapflap - pause - ...".

When I connect my Aquaris to my A2DP speakers at home, the audio is perfect.

Also, handsfree telephony in my car works like a charm.

So I guess it's just the combination of A2DP while connected to the handsfree device which causes the trouble.

In the past I've used several phones with the Funkwerk device (always with handsfree *and* A2DP functionality) including an N900 running Maemo. There have never been any problems with those.

Just a quick note to confirm that the problem persists after updating to OTA-4.

There were two postings on the mailing list that seem to allude to the same problem:

Please help.

Can someone who experience this problem here follow the steps on https://wiki.ubuntu.com/Process/Merges/TestPlan/ubuntu-system-settings#Bluetooth-1 so that we get logs files with debugging for bluetooth components enabled to further analyze what the problem here is?

According to testplan/bluettoth debugging:

/var/log/syslog

may I add my own "syslog" file:

the other requested file ( home/phablet/.cache/upstart/application-legacy-ubuntu-system-settings-.log) is not available.

Sorry, I was being too fast. It only works if I initiate the connection from the phone. When the handsfree device connects automatically, the problem persists as described.
