Hi all,
I get an runtime error, when switching a valve.
I saw a similar problem some months ago, but the setup was different.
My setup is quite easy:
A signal source ( cosine, float ) connected to a audio sink.
The same signal source is connected to a valve and the valve is
connected to a scope sink.
The valve is switched by a checkbox.
Switching the valve leads to
audio_alsa_sink[hw:0,0]: snd_pcm_hw_params failed: File descriptor in
bad state
terminate called after throwing an instance of 'std::runtime_error'
what(): check topology failed on audio_alsa_sink(1) using ninputs=1,
noutputs=0
I wonder how the valve affects the audio sink.
Any ideas ?
Thanks in advance
Volker
