Audio stops working on repeated play of MKV file

[Jani Uusitalo]

With just one file on the playlist and looped (with repeat mode on), at about 0:24 during the second play the audio goes mute and doesn't recover by itself. Restarting the video by double-clicking on the playlist item makes the audio come back.

The funny thing is, if you add another MKV file to the playlist and let it loop between the two files, there's no problem. But with the single file repeating it looks to be 100% reproducible.

Doesn't seem to be reproducible using MP4 or AVI files, just MKV. Not reproducible with VLC. I've thus far found at least two MKV files [1], [2] that reproduce this 100 %. IIRC, the issue didn't occur with these same files back in Lucid.

Steps to reproduce:
1. Download one of the aforementioned MKV files.
2. Load it in Totem.
3. Set 'Repeat Mode' on.
4. Play the file, wait for it to loop.

What happens:
At about 0:24 during the second play the audio goes mute.

What I expect to happen:
The audio to continue playing normally during the second and subsequent loops also.

I should supplement "add another MKV file to the playlist and there's no problem" with that the second file could also be the same file, so that the playlist is comprised of two instances of the same file. This way it works audiowise the way it should even with the file there just once, so it's an effective, albeit silly workaround.

I've found an MP3 file that also exhibits this. Can't link it for © reasons, but I've got it here for testing.

[Jani Uusitalo (uusijani)]

Actually, with the MP3 it's Bug #918077 (which I just reported). Could be the same underlying issue, but I felt it best to report these separately as the symptom differs slightly.

[Bryce Harrington (bryce)]

The upstream fix for bug #918077 is included in Precise. Can you re-test this issue on precise and report whether that fix fixes this issue as well?

[Jani Uusitalo (uusijani)]

That's a negative: this one persists.
