Have since installed Audacity and Audacious which work fine.
Rhythmbox behavior has changed but remains reproducible.
New Info:
If I select a source from within Rythmbox library I get a File error. Same if I try to Import file by browsing. See RB01.png.
However, if I right click on audio file in File Browser and try to play with Rhythmbox, I get Pipeline error. See RB02.png

Is the file listed there availabe? Could you get a rhythmbox --debug log to get details on the issue?

How do I do that?

I removed Rhythmbox with Synaptic, then reinstalled, and it started working again.

Same problem for me - I uninstalled and reinstalled via Synaptic, and all good to go.

I also had this problem particularly with the BBC asx streams - but on re-installing from Ubuntu Software Centre I noticed that it recommended installing python-coherence. I installed this and all gstreamer plugins and I can now play these streams after a second or so of buffering.

I'm having this problem, RhythmBox gave me an error about failing to start the playback pipeline. I don't remember the exact wording, I can't get it to display the message again.

Everything was working fine until Amarok crashed.

Amarok is cool, but it plays hell with my sound settings, this is not the first time.

I've started the fix by totally removing Amarok.

Next, I'll investigate ALSA utilities. I know I can fix it, but I always forget how.

My problem was associated with the installation of 9.10.
First I 'upgraded' with the online version. Several applications including Rhythmbox then malfunctioned.
Then I burned a CD and re-installed from that - some problems disappeared but I still could not get my audio set-up right.
Finally I erased the entire partition and made a clean installation. All is now well.
Seems that something hanging over from 8.04 is not properly updated during installation of 9.10.
Perhaps with time and patience I could have tracked down the precise problem but life's too short!

I have this error message as many other users on ubuntu-fr forums while playing certain web radios.

I'm using a plugin created by segler-alex (ppa available) in order to access web radios. Certain web radios url are simply obsolete in the database provided by the dev of the plugin. Here's what Rhythmbox (actually Gstreamer) says in terminal:

jelly@superdupont:~$ rhythmbox --gst-debug-level=1

0:00:59.922836820 11272 0x48e28e0 ERROR mmssrc gstmms.c:445:gst_mms_start:<source> Could not connect to this stream, redirecting to rtsp

In frontend Rhythmbox gives the "pipeline" error message.

So it seems that Gstreamer doesn't like redirections.. If I correct the plugin with the new url, it works fine.

I understand that the original bug described here is quite different. But I think it just might be a Gstreamer issue for everyone.

I'm also having this problem with RhythmBox after a clean install of 9.10 I get the error "Unable to start playback pipeline" This happens when I try to play an audio CD in Rhythmbox but not when playing audio files already saved on the PC.

I believe it maybe linked to this though? Sometimes when I double click on the Rhythmbox desktop icon the little wheel will spin around for a few secs but it won't open. Then when I click a second time it opens.
Again if I insert a CD and the msg box come up asking what to do, i.e launch Rhythmbox. I click on open and it tries to open but fails. If I theneject and reinsert the CD and try again it always opens second time.
