Description Christophe Fergeau 2004-03-09 19:49:46 UTC 
gst-mixer checks if an element implements the property probe interface
before using it. Since the alsa element doesn't implement it, it can't be
used by gst-mixer, which means no native alsa mixer support.
Comment 1 Ronald Bultje 2004-03-09 22:31:19 UTC 
Thanks for looking this up! I was intending to install ALSA one of the
next few days so we could fix this right before 0.8.0... This makes it
a lot easier.

If anyone else wants to shoot first, please go ahead; I'll be glad to
give any assistance in implementing it.
Comment 2 Christophe Fergeau 2004-03-09 22:42:47 UTC 
To make things perfectly clear, gst-mixer works with alsa when you
enable oss emulation (I fixed that about 10 days ago), it's only if
you want native alsa mixing that it doesn't work.
Comment 3 David Schleef 2004-03-09 23:00:24 UTC 
Sort of.  OSS-based mixers aren't able to set the ALSA mixer settings
correctly on my hardware in all cases.
Comment 4 Benjamin Otte (Company) 2004-03-10 22:10:14 UTC 
FWIW, I don't have any devices to select in gnome-volume-control. They
are working fine in gkrellm.
I only get controls for /dev/dsp. But that one works fine.

This is alsa emulation (/dev/dsp[01]) and normal OSS (/dev/dsp2) with
most recent CVS of gnome-media and gst.
Comment 5 Ronald Bultje 2004-03-13 04:45:11 UTC 
Fixed in CVS.
