Hi I have a problem with the audio sink. I'm playing around with the analysis_filterbank block. I have a GUI allowing the user to pick a channel. That channel then gets connected to an FM demodulator,volume control and finally an audio sink. At the start of the app, I initialise everything and the audio sink works. As soon as I change a channel by reconnecting everything, I get this error:
audio_alsa_sink[plughw: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(8) using ninputs=1, noutputs=0 Aborted Can someone please tell me what might be wrong? Thanks. Sebastiaan _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
