need to get working with cli-visualizer

[djloot]

I assume this will require fifo of some type but can't figure out how to get the slave.pcm defined. here is the section in the documentation for the system:

ALSA setup config

pcm.!default { type file # File PCM slave.pcm "hw:0,0" # This should match the playback device at /proc/asound/devices file "|safe_fifo /tmp/audio" #safe_fifo will be in the cli-visualizer/bin/safe_fifo directory format raw # File format ("raw" or "wav") perm 0666 # Output file permission (octal, def. 0600) }

Your idea looks good. I don't have an example for piping to fifo off hand.

Out of interest, does the audio have to go to file/fifo ? Can you pipe directly in to your cli-visualizer ?

It doesn't have to go fifo, just don't know enough about the code to set it to go directly to the alsamixer. It says to to match /proc/asound/devices. For me, it looks like this: 0: [ 0] : control 16: [ 0- 0]: digital audio playback 24: [ 0- 0]: digital audio capture 32: [ 1] : control 33: : timer 48: [ 1- 0]: digital audio playback 49: [ 1- 1]: digital audio playback 56: [ 1- 0]: digital audio capture 57: [ 1- 1]: digital audio capture

Oh - I don't quite understand how cli-visualizer works.

Does it present as an ALSA device or a different way ?

thanks

Matt

I honestly don't know. It looks like it was developed kind of based on CAVA. I got CAVA working perfectly with the sound card but also wanted cli-visualizer.
