gstreamer 0.10 : High CPU utilization when alsasrc is disconnected

[karthikuppund]

Hi,

I am observing high CPU utilization (~78%) when alsasrc is disconnected. Particularly audiosrc-ring buffer is shooting high. I am using iphone as alsa device.

Below is the pipeline I am running on imx6 board:

gst-launch-0.10 alsasrc device=hw:x,y ! audiconveert ! audioresample ! autoaudiosink

Steps to reproduce:

1. run gst-launch-0.10 alsasrc device=hw:x,y ! audiconveert ! audioresample ! autoaudiosink
2. disconnect alsasrc ( iphone in my case)
3. run top -p <PID of gst-launch-0.10>H

Frequency of reproducibility :ALWAYS

This issue is not observed in gstreamer 1.0. The audiosrc-ring buffer vanishes as soon as alsasrc is disconnected in gstreamer 1.0

Hello,

  Looks like a bug in alsasrc - perhaps it makes sense to try

the recent BSP or use the gstreamer 1.0
