Description Reuben Thomas 2004-07-23 15:41:17 UTC 
1. Play an ogg file.

2. Pause it.

3. Start playing again.

The sound quality is now poor (full of hiss and crackles). Restarting the track or moving to another 
cures the problem.

I'm using rhythmbox 0.8.5, built with gstreamer 0.8.4 and gst-plugins 0.8.2, all built from source, on 
Debian sarge.
Comment 1 Reuben Thomas 2004-07-23 15:47:55 UTC 
I have exactly the same problem if I pause the playback of an MP3 file.
Comment 2 Reuben Thomas 2004-07-26 16:27:16 UTC 
This seems to depend on the gstreamer backend being used. When I reported this bug I was using 
osdsink. I changed the sound sink to esdsink so rhythmbox would share the sound card with other 
programs, and that cured the problem.

Hence it looks as though it's a gstreamer problem, not a rhythmbox problem.
Comment 3 Reuben Thomas 2004-08-04 09:32:55 UTC 
I'm now getting the problem again (most of the time, but not always) with esdsink as well.
Comment 4 Reuben Thomas 2004-08-05 15:43:44 UTC 
I've just narrowed down the problem further. I don't think it matters which sound sink is used. The reason that the 
problem is only apparent sometimes is that with most commercially recorded CDs, it is not audible (presumably 
because the noise level is already very low).

With CDs recorded live (either by myself, or commercially), the effect is audible: after pausing, playback is noisy. This is 
independent of the sound sink, and of whether the file being played is an MP3 or an OGG file.

It's a GSTreamer bug afaik.

Reuben do you have any sample files you can attach? It is next to impossible to
debug this without that I think.
Comment 8 Reuben Thomas 2004-12-21 15:23:27 UTC 
I've just tried with the latest version of gstreamer and rhythmbox in Debian 
sarge, and I no longer get this problem.

thanks for the feedback, closing
