[mythtv-users] Playback issues after 12.04 > 14.04 upgrade

[Martin Moores]

Hi all,

Been battling this one for a few weeks now and no joy fixing it.

Upgraded from 12.04 > 14.04 and all seemed fine.  But I now find when
trying to start any playback, mythfrontend just hangs on "please wait".
This happens on recordings and mythvideo.  The video does start playing
after 7/8 minutes if left on the "please wait" screen, but audio is either
choppy (and video skips/fast forwards randomly) or the audio doesn't play
but video displays fine, which seems to be happening on the last few tests.

It does however work after a reboot, but then trying again in a few hours,
it will hang again.

I first thought it must be video drivers, so reinstalled Intel stuff, tried
turning VAAPI off (normal playback profile), but no joy.

Seem to have tracked it down to an audio issue due to other things.  For
example, if I navigate to the audio menu in the frontend, this also crashes
mythfrontend.

There is some stuff mentioned in the logs:

mythfrontend -v playback,audio (starting frontend and attempting playback
of recording, waiting for playback to eventually start):

I have tried reinstalling bits of ALSA and Pulse, removed asoundrc config
files from etc and home dir.

I did wonder if this is some sort of HDMI sleep issue, have seen many posts
about this happening when PCs resume from sleep, which is not the case
here, but did try a different HDMI cable and port in my TV, with no change.

Also tried the different audio devices, hw, hdmi, dmix and plughw

Any pointers appreciated!

Cheers

Martin
