[gst-devel] Problems with USB speakers

[Stefan Kost]

Hi,

I suspect that the driver is bahiving strange. Can you run:

GST_DEBUG="alsa*:5" GST_DEBUG_NO_COLOR=1 gst-launch-0.10 2>debug.log filesrc
location=my.ogg ! oggdemux ! vorbisdec ! audioconvert ! audioresample ! alsasink
device=hw:1

and post the log?

Stefan
