[gst-devel] issue on alsasink in version 0.10.0

[rong wang]

I tried to run following command 
gst-launch audiotestsrc ! alsasink

then there is no sound coming out, also, it hangs, I
cannot use control-c to come out.

On the same board if I used following board
gst-launch audiotestsrc ! osssink

then I can hear the sine tune coming out.

After running gst-launch audiotestsrc ! alsasink

I got following result:

gst_alsasink_get_typr
gst_alsasink_base_init
gst_alsasink_class_init
gst_alsasink_init
Setting pipeline to PAUSED ...
gst_alsasink_open

gst_alsasink_delay
gst_alsasink_get_typr
New clock: audioclock0
gst_alsasink_get_typr
gst_alsasink_write
Just before snd_pcm_writei  operation


some debug message are what I added in alsasink.c.
currently, I know it never come back from
snd_pcm_writei function.

Thanks for the advice in advance.

Rong
