playback pauses after two songs, even with repeat enabled

[Tom Haddon]

If I set playback with repeat on, playback still pauses after two songs for me in rhythmbox. It pauses at the start of a song, but the controls show it's still playing (i.e. the "pause" button is there for me to pause the song, rather than the "play" button). If I click the slider anywhere in the timeline of the song, playback continues. If I leave things playback will resume after some time (maybe five minutes or so), but will be stutter-y and jump ahead in songs.

[Vadim Rutkovsky (roignac)]

Thank you for taking the time to report this bug and helping to make
Ubuntu better, however the report is missing some information, may you
please run rhythmbox as: rhythmbox --debug &> rhythmbox-debug.txt ;
perform the steps to reproduce the bug and attach that resulting log
file to the report? Thanks in advance!.

[Tom Haddon (mthaddon)]

Attached debug output as requested.

[Bryce Harrington (bryce)]

I notice in your log that your music collection is a mix of ogg and mp3. Could this be the same as bug 921071 or bug 969855?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Tom Haddon (mthaddon)]

Yep, I believe this is a duplicate of bug 921071 (can reproduce by going from mp3 -> ogg) but the suggested solution of enabling crossfade doesn't seem to work for me.

[Otus (jan-varho)]

I can reproduce 100% of the time and crossfade doesn't help. Playback sometimes continues after a while (3-4 minutes in the most recent case I saw) and the song jumps to a position close to where it would have been if it had been playing from the beginning.

The following transitions cause a pause:
  mp3->ogg
  mp3->flac
  ogg->flac
  flac->ogg

These do not:
  ogg->mp3
  flac->mp3

I don't have other media types in the library to test with.

[Alistair Buxton (a-j-buxton)]

Just marked my bug a duplicate. I also have a mixture of different formats. MP3, OGG, WAV, and others.

[lljccoael (lljccoael-deactivatedaccount)]

I have the same bug and observe exactly what Otus reported.

[Mattias Johnsson (m-t-johnsson)]

I also have this problem. I can confirm Otus' findings on what transitions cause the hang.

If I enable crossfade, instead of hanging indefinitely on transition, there's about a 5-10 second hang, then Rhythmbox skips partway into the next song and carries on as normal.

[Reinhard (reinhard-fink)]

I just could reproduce the mistake in a fresh install of 12.04 amd64:

The following transitions cause a pause:
  mp3->ogg

These do not:
  ogg->mp3

I thing bug https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/978604 deals with the same problem.

kde - player amarok has the same problem.

in syslog i find:

pulseaudio[1900]: [alsa-sink] ratelimit.c: 56 events suppressed
pulseaudio[1900]: [alsa-sink] protocol-native.c: Failed to push data into queue

sound in 11.04 was ok.

[Thomas (birkenfeld)]

I can also confirm this problem. I have also a mixture off mp3 and ogg files.
With Ubuntu 11.10 it works fine.

[bitinerant (bitinerant)]

I can confirm that this did not happen on 11.10 with the same music collection. I have ogg, mp3, and wma.

[jederzeit (6d4b449ce132)]

I experience the same bug on a fresh 12.04 i386 install. My music collection consists of MP3 and OGG Files. As described the bug manifests itself, wenn an MP3-file is followed by an OGG file.

[Sebastien Bacher (seb128)]

Undupping, it's not clear they are the same issue since bug #978604 happens without format change

Could somebody having the issue report the bug upstream: https://bugzilla.gnome.org/enter_bug.cgi?product=rhythmbox

Including a rhythmbox --debug and maybe a GST_DEBUG=:5 rhythmbox log when getting the issue could be useful

[George Schneeloch (noisecapella)]

I think this upstream issue is the same bug being discussed here: https://bugzilla.gnome.org/show_bug.cgi?id=676689

[Reinhard (reinhard-fink)]

I am using amarok - kde player and can reproduce the bug when changing from mp3 to ogg.

So I think the problem comes from pulseaudio or deeper.

[Otus (jan-varho)]

I doubt PA has anything to do with it, but gstreamer might. In any case, does the upstream link mean this is no longer incomplete?

[Sebastien Bacher (seb128)]

the rhythmbox upstream asked for a "GST_DEBUG=*:3 rhythmbox -D player" log of the issue, note that bug #978604 which is similar is opened against pulseaudio

[nocheiner (7d9a25a2d1a9)]

Here the "GST_DEBUG=*:3 rhythmbox -D player" log of the problem from my machine

[Sebastien Bacher (seb128)]

seems like it should be fixed with http://cgit.freedesktop.org/gstreamer/gst-plugins-base/commit/?h=0.10&id=38803239c026163589dde04259b00c5fe33ad706
