FreeBSD/sndio issue

[plasmoduck]

Hi there, can you create a new feature for cava that picks up any audio input from alsa, pulseaudio etc. Say I'm listening to a music video on YouTube in my browser so cava can display the audio visualisation. Perhaps this feature can be started with a flag like 'cava -l' for listen.

Not sure if I understand. Cava already picks up audio from specified alsa or pulseaudio interface.

If pulseaudio is installed it should use the default output automatically. This will work out of the box in most cases.

Are you suggesting to listen to all inputs it can find, simultaneously? And visualize everything? On top of each other?

[plasmoduck]

At the moment cava ONLY works with ncmpcpp. Can you make it work with firefox etc also? So if Im watching some video/audio through firefox cava with pick it up.

I think you got cava confused with the built in visualizer in ncmpcpp.

Just read the readme on capturing audio:

https://github.com/karlstav/cava#capturing-audio

[plasmoduck]

Hmm, doesn't work for me. It only works with ncmpcpp/mpc etc

[karlstav]

then go through the readme step-by-step or read more about audio in linux here:

If you still cant get it working, feel free to post a bug report. Create a new issue and use the included template.

Yes I've been though the readme. Problem is I use FreeBSD with Pulseaudio on an old 'Late 2012, 27" Core i5 iMac" as there is no alsa etc in FreeBSD and the Apple hardware may be limiting me.

[karlstav]

I use FreeBSD with Pulseaudio

now you tell me. This is probably the cause of your problem. Can you give me the output of pacmd list-sinks and pacmd list-sources? There is also sndio, but I fear it might be broken

[plasmoduck]

No PulseAudio daemon running, or not running as session daemon. for both commands.

that complicates things, I think maybe your best bet is the sndio input.

[plasmoduck]

I tried that, following the instructions on the cava guide. I issue the -dd -s default -m mon -s monitor command then the AUDIODEVICE=snd/0.monitor cava command and cava launches but doesn't pickup any sound except for mpd/mpc/ncmpcpp I'm at a loss with this I think. It's not such a big deal I guess. Just would have been nice to look at cava when playing music through my browser on youtube.

This is the settings I use to get sound out my headphones on FreeBSD /boot/loader.conf

hint.pcm.2.eq=1 hint.pcm.3.eq=1 hint.hdaa.1.gpio_config="0=keep 1=keep 2=set 3=set"

strange that mpd still works. how does your cava config look? Did you remember to comment out the mpd input? It you used that earlier.

[plasmoduck]

I'm using fifo input

method = fifo source = /tmp/audio.fifo sample_rate = 44100 sample_bits = 16

thats the only one that works

[karlstav]

I meant fifo input.

if you use fifo input cava will only work for applications that output to the selected fifo. Firefox can not do that.

Unfortunately the sndio input is poorly documented in cava, try to set:

method = sndio

and comment out everything else.

then follow the instructions here:

https://github.com/karlstav/cava#sndio

[plasmoduck]

I tried that, it doesn't work with default for 'sndiod -dd -s default -m mon -s monitor' how can I get a list of the outputs to try?

[karlstav]

I would not know, don't really know FreeBSD/sndio.

[plasmoduck]

All good. I might close this issue then. Thanks for the help.
