DO we somehow need to reset the state. The first rate check fails with "unsupported rate", all further already fail when setting the format.

Comment 3 Tim-Philipp Müller 2008-04-08 19:50:31 UTC

Does this also happen with  osssrc ! fakesink  or  audiotestsrc ! audioconvert ! osssink, or only when using both together in a pipeline?

Comment 6 Tim-Philipp Müller 2009-08-01 20:00:20 UTC

Sounds like something only you really can figure out tbh .. maybe a driver problem?

Comment 7 Tobias Mueller 2010-03-02 12:33:27 UTC

So, what are we going to do about this bug? Closing as NEEDINFO soonish?

Comment 8 Stefan Sauer (gstreamer, gtkdoc dev) 2010-03-03 14:07:49 UTC

Just tried and at least the probalm is still there. And the problem is that sys/oss/gstosshelper.c 
gst_oss_helper_probe_caps() hard codes channels to 2. I'll try to make a patch.

Comment 9 Tobias Mueller 2010-04-20 00:14:50 UTC

Reopening as per last comment. Stefan, feel free to assign this bug to yourself to indicate that you're working on a patch :)

Comment 10 David Schleef 2010-12-05 00:00:15 UTC

*** Bug 538068 has been marked as a duplicate of this bug. ***

Comment 11 Tim-Philipp Müller 2012-10-23 16:51:28 UTC

Doesn't look like this will ever get fixed, and possibly/likely a driver problem, so let's close it.
