Hi All,
Does anyone have idea about the log ?
that gstreamer can not play wav file to usb audio alsa device.
I use the command to play audio to usb alsa audio device.
gst-launch-0.10 -v filesrc location=/bin/audio_src_48k_le.wav !
wavparse ! audioconvert ! alsasink device="hw:0,0"
It is OK by "aplay" utility, but it is fail by gstreamer launch
