Audio Input does not work

[raphael303]

I have setup audioenc - dabmux - dabmod and all works with an audio stream from an url.

This: odr-audioenc -v "https://eatv.radioca.st/stream" -r 48000 -c 2 -o "tcp://localhost:9003" -l -b 192

Will result in proper encoding.

This: odr-audioenc -d hw:0,0 -r 48000 -c 2 -o "tcp://localhost:9003“ -l -b 192
or this: odr-audioenc --device=hw:0,0 -r 48000 -c 2 -o "tcp://localhost:9003“ -l -b 192
or this: odr-audioenc --device=sndrpihifiberry -r 48000 -c 2 -o "tcp://localhost:9003“ -l -b 192
or this: odr-audioenc --device= snd_rpi_hifiberry_dacplusadcpro -r 48000 -c 2 -o "tcp://localhost:9003“ -l -b 192
or this: odr-audioenc -d snd_rpi_hifiberry_dacplusadcpro -r 48000 -c 2 -o "tcp://localhost:9003“ -l -b 192

Will all result in a hanging prompt.

My aplay -l looks like this:

**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_dacplusadcpro], device 0: HiFiBerry DAC+ADC Pro HiFi multicodec-0 [HiFiBerry DAC+ADC Pro HiFi multicodec-0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Any ideas?

Addition I tried a workaround with the same result:

jackd -d alsa --device hw:0,0 --capture -n MyJackInput
odr-audioenc -j MyJackInput -r 48000 -c 2 -o "tcp://localhost:9003“ -l -b 192

Also, I tried recording audio with "gnome recorder" this also worked.

Hi, is this solved for you now with -d plughw:1,0 ?

[raphael303]

Sort of. It does work, but imho if it is supposed to work with any of the above commands it is inherently a problem with newer linux releases or a bug. From what I experienced I'd say that the problem lies in the format. It is unclear what the encoder expects and it can not be defined. plughw seems to work because alsa does some "conversion magic" in the background. But that of course leads to more latency and imho overall another layer which can cause problems.
