so... all this mess is born by asound.conf, without it moode run fine, just spectrum loopback missing...
i hope will me another easiest way to create loopback for cava...

thanks

Hi Fabio

I can't see any obvious issues in your configuration, and so I don't have any further suggestions (except to check that your volume is up!). I believe the loopback can be configured on your setup, so you might want to search the internet for a solution. Otherwise, you could undo your modifications for the loopback and use the MPD FIFO method to create a copy of the audio (which only gives a spectrum for music playing through MPD).

Adrian.

fabio323ti · 04-14-2020, 08:52 AM

hallo Adrian, just to know, last night installed "volumio" and also there loopback is created and working without any output audio from 3.5 jack.
i used your settings from "github issue", i remember you that at moment i don't use any DAC i2s board....

so i will try for last Mpd fifo method for loopback but i have no instructions about it.. how can be done it?

many thanks

Malefoda · 04-14-2020, 08:57 AM

Adrian, can you update the missing wiring image in your second message?
Thanks!

adrii · 04-14-2020, 09:40 AM

Hi Fabio

Your mpd.conf file already contains the section to output the FIFO for mpd_oled (from following the mpd_oled installation instructions), so just run mpd_oled without the '-c' option.

Adrian.

adrii · 04-14-2020, 09:54 AM

Hi Malefoda

My second message in this thread is #5

http://moodeaudio.org/forum/showthread.p...44#pid1444

and I can see all the images in it (I believe!).

A couple of days ago I had a report that the links to the images in the mpd_oled installation instructions were broken, so if you meant these images then this is now fixed.

Adrian.

fabio323ti · 04-14-2020, 11:22 AM

Thanks Adrian, default settings FIFO are ok, and without -c working fine... but main purpose is to show cava from streaming... spotify or other external source.

will leave as is, too much time waste on stupid cava.. When some engineer will complete plugin will try change. For me its uncomplete and half-useful .

Hi Adrian,
sadly just after the "I wire it like this" line there is a missing image. But if it's the instructions it's not that critical Wink

Here is what I get:

@Malefoda

I'm not sure why, but in my browser, I see the same "[Image: Raspberry-Pi-...jpg]" you see BUT the image itself follows the paragraph which begins "If you are using a PI 1 or 2...."

Browse directly to the image and you'll see what I mean: http://4.bp.blogspot.com/-L3-iYP2DCBo/Uc...1098cd.jpg
