Summary: gstreamer fails to detect alsa device required Hz
Product: GStreamer
Version: 0.10.11
Platform: Other
OS/Version: Linux
Status: UNCONFIRMED

GNOME version: Unspecified
GNOME milestone: Unspecified
USB speakers on a system with ALSA play perfectly when using mplayer or when
setting it to use gstreamer+plughw, but not when using gstreamer+hw.
1 - MPlayer output when playing an ogg file (indicates a 48KHz as output):
==========================================================================
Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
AUDIO: 44100 Hz, 2 ch, s16le, 192.0 kbit/13.61% (ratio: 24000->176400)
Selected audio codec: [ffvorbis] afm: ffmpeg (FFmpeg Vorbis decoder)
==========================================================================
AO: [alsa] 48000Hz 2ch s16le (2 bytes per sample)
2 - gst-launch:
gst-launch-0.10 filesrc location=my.ogg ! oggdemux ! vorbisdec !
audioconvert ! audioresample ! alsasink device=hw:1
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /pipeline0/alsasink0: Could not get/set settings
from/on resource.
Additional debug info:
gstalsasink.c(570): set_hwparams (): /pipeline0/alsasink0:
Rate doesn't match (requested 44100Hz, get 0Hz)
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
FREEING pipeline ...

Changing output rates from 44.1KHz down to 8KHz results in the same error. See
attached debug.log for above gst-launch command.
Please let me know if any further information is needed.
