Hi Thomas,

Two things to try so that we can narrow down to a definite cause.

1)  Put a queue (see below pipeline) right before alsasink and rerun test (if
you have not already tried placing a queue right before alsasink already).

gst-launch-1.0 -v alsasrc device="$alsa_iface" ! audioconvert !
audioresample ! "audio/x-raw, format=S16LE, channels=2" ! queue ! alsasink
device="$alsa_iface" sync=false

2)  Cut the number of channels down to one (see below pipeline) and rerun test.

gst-launch-1.0 -v alsasrc device="$alsa_iface" ! audioconvert !
audioresample ! "audio/x-raw, format=S16LE, channels=1" ! alsasink
device="$alsa_iface" sync=false

Best Regards,

Rob

P.S. I know that this is monotonous and tedious.  I just got done fixing a bug
that required me to do numerous runs of a pipeline over 24->48 hour periods to
identify, fix and test.
