Hm. I though it might be some infinity-loop in our IO-layer-chain, but
migh quick test with selecion, without selection and the same with sample
date available and withou never caused such a situation (although I have
ALSA's OSS emu here ...). What situation do you need to causse this?
(a files loaded (or not), a selecion (or none), ...)
btw: some more informations about gsmp. We have multi-selections and markers.
Multi-selection is performed by using the "Shift" or "Meta" Key (add or
substract). Marker support in the UI is very limitted. You see the IO-pos
muving during playback / capture and you can set the current-editing-pos
marker by short clicking into the wave-form. This is the position where
IO starts ... (I write a new waveform using a overlay-technic simillar to
Ardours in the next weeks - with full marker, better selection, real-grid,
and sample-index labeling, and evelopes)

It should be either the ALSA node or some part of out "filters" in
the IO chain. GSML/include/IO.hh:
/* There are additinal MixerSource classes that can be stacked upon each other
* and act as filters (mainly) for the DataLayer source. That way we implement
* looping and Markers (limmiting and modifing of the start, end and current
* position ...):
*
* DataSource <-> SelectionFilterSource <-> (MultiplexerSourece) <-
* -> MarkerFilterSource <-> LoopFilterSource <-> Mixer <-> MixerNode
*
* A Multiplexer Source suppots switching the SourceChain. This is mainly used
* to switch to a FX prehearsal stream.
*/
But I will also fix it if I get more info ;-)
