test app

When using alsasrc with S/PDIF input, starting/stopping pipeline works perfectly. But when disconnecting cable during playback (or changing sample rate, stopping the signal) and setting the pipeline to NULL state causes a deadlock.

Log also prints the following message:
alsa gstalsasrc.c:864:xrun_recovery:<alsasrc> xrun recovery -5: Input/output error

Please see attachment for example app.
Comment 1 Manuel Weichselbaumer 2018-04-18 20:24:21 UTC 
It also seems, that digital audio input is not handled very well in Linux.

Currently, there is no (easy) way to handle rate changes from an external clock generator (e.g. S/PDIF signal) and forward to user-space app.

From my point of view, I'd be ok, if the alsasrc just stops whenever there is a rate change or signal disconnection.
