Alsasink problem?
Locked
 
|
Hi,
I have ALSA driver for my card and it works fine when I try playing sound through aplay or watch movies through gstreamer, but if I try to do: gst-launch-0.10 filesrc location=FILE_NAME.ogg ! oggdemux ! vorbisdec ! audioconvert ! audioresample ! alsasink it comes back: Pipeline is PREROLLING ... ERROR: from element /GstPipeline:pipeline0/GstAlsaSink:alsasink0: Could not get/set settings from/on resource. Additional debug info: gstalsasink.c(519): set_hwparams (): /GstPipeline:pipeline0/GstAlsaSink:alsasink0: Unable to set hw params for playback: Invalid argument ERROR: pipeline doesn't want to preroll. Setting pipeline to NULL ... So it comes back that alsa cannot setup correctly even though alsasink works correctly when I play MPEG movies. any thoughts?

Can you try to use alsamixer, aplay and arecord to test if your driver is working correctly?

Yes this is an embedded system. As I stated in my previous post aplay, alsamixer and playing MPEG4 movies through gstreamer works just fine. Problem occurs when I try playing ogg files through the pipeline specified.

does this pipeline works for you
gst-launch audiotestsrc ! alsasink -v

gst-launch audiotestsrc ! alsasink -v
works no problem. I have realized that if I play the song using virtual device instead of the real device the thing works just fine. I have made the virtual device as: pcm.mydev { type plug slave { pcm default rate 32000 } } My driver supports all the rates from 8KHz to 48KHz, but it seems to me that the rate in this song is different than what my driver supports. Is this rate conversion suppose to happen in ALSA automatically or I have to use ALSA through virtual device in order to get unsupported parameters to work on my driver? If so, is it possible to specify multiple rates in my virtual device or I have to have one rate only? Cheers, Ogi On Wed, Dec 29, 2010 at 10:21 PM, praveen pandey <[hidden email]> wrote:

In reply to this post by ogara
I am having a similar problem, did you find an answer of solution? My sound card is working and the driver and ALSA drivrs. I can test the sound and get audio thru both speakers. However something has a hold on my sound output. Does someone know how to detect what has it locked from being accessable? How to breack that connection to free it?

The problem I was facing was in the unusual rate from the source song. I have defined the virtual device in my .asoundrc file and I am using this device to play all the content. It seems to me that the alsa-lib is controlling virtual device so if the content is not match to hardware specs it will resample the data to match hardware profile.
