Bug#578121: gstreamer0.10-alsa: alsasink as input seems to not work by default with a 48kHz-only input device

[Ari Pollak]

Package: gstreamer0.10-alsa
Version: 0.10.28-1
Severity: normal

(I have no idea where to put this bug, so I'm assigning it to the most
obvious package)

In trying to set up audio input through a USB Logitech QuickCam Pro
9000, which only supports mono (1 channel) 48kHz audio, I discovered that
alsasink by itself didn't work.
If I went into gstreamer-properties and tried to set the audio input
pipeline to 'alsasink device="hw:1,0", I got the following error on the
console when trying to test it:

gstreamer-properties-Message: Error running pipeline 'Custom': Could not
get/set settings from/on resource. [gstalsasrc.c(437): set_hwparams ():
/GstPipeline:pipeline7/GstAlsaSrc:alsasrc8:
Rate doesn't match (requested 44100Hz, get 0Hz)]

If I change the pipeline to this, it seems to work fine:
alsasrc device="hw:1,0" ! audioresample ! audio/x-raw-int,rate=48000

That would be pretty obscure to an end user trying to set up this webcam
for videoconferencing, so I hope there's a way to get it autoconfigured
properly. I should note that ekiga and arecord don't need any special
configuration to get it to work.
