Hi everyone,
I'm having problems making the audio output work because of a "RuntimeError:
check topology failed on audio_alsa_sink(7) using ninputs=1, noutputs=0". I
did spend a few hours searching the archives and the web, but no luck.
Hardware: RPi model 3, the signal comes from an RTL-SDR dong

Thank you for your help Johnathan. Looks like I figured out the issue with Alsa
and opened the channels using alsamixer. I was choosing the wrong hardware and
now I am using hw:00,04 which seems to work with sampling rate 44.1K.
command line: sudo ./tx_voice.py -f 991e5 -v -I hw:00,04 -M 1

Then it appears you either don't have an ALSA input configured, or it
does not support 8000 Hz sampling rate.

Can anyone please tell me that why I am getting the following message when
running tx_voice.py:
>>> gr_fir_fff: using SSE
Warning: failed to enable realtime scheduling
audio_alsa_source[hw:0,0]: set_channels failed: Invalid argument
