[op25-dev] Audio to Darkce/IceCast Server - No audio???? No tags, Local audio good.

OK... I've put my RPi3B+ to work... Raspbian Image, updated, fully loaded.. (NOT NOOBS, this is just Raspbian Full ) Run through the install setup for OP25 from: https://www.hagensieker.com/wordpress/2018/07/17/op25-for-dummies/ Did this for my reclaimed laptop and this Pi... OP25 working on both... Local audio good on both. Tracks the PII system I need to put under review... So that works good.. The problem is feeding audio to my IceCast server.. :( :( :( I installed a MP3 capable Darkice with its deps... its starts up fine.. The feed appears on my server I am using the info at https://www.hagensieker.com/wordpress/2018/07/20/op25-raspberry-pi-streamin… I created /etc/asound.conf and /etc/modprobe.d/bcm2835.conf I rebooted the Pi rather than any reloading of things, to ensure that loopback created and loaded etc... For the ALSA Loopback etc. info and setup..... so is the ALSA loopback setup???? /darkice $ cat /proc/modules | grep snd snd_aloop 24576 0 - Live 0x7f3a6000 snd_bcm2835 32768 1 - Live 0x7f399000 (C) Check! Pi audio and ALSA loopback... CHECK CHECK! snd_pcm 98304 2 snd_aloop,snd_bcm2835, Live 0x7f138000 snd_timer 32768 1 snd_pcm, Live 0x7f11d000 snd 69632 6 snd_aloop,snd_bcm2835,snd_pcm,snd_timer, Live 0x7f102000 ALSA seems to be a dark arts thing.. I use some plugins on another setup to create L/R into separate feeds into darkice and that works great.... so I took it this loopback thing would do the same... Seems the loopback exists....from: ~/darkice $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA] Subdevices: 7/7 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 Subdevice #3: subdevice #3 Subdevice #4: subdevice #4 Subdevice #5: subdevice #5 Subdevice #6: subdevice #6 card 0: ALSA [bcm2835 ALSA], device 1: bcm2835 ALSA [bcm2835 IEC958/HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Loopback [Loopback], device 0: Loopback PCM [Loopback PCM] Subdevices: 2/2 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 card 1: Loopback [Loopback], device 1: Loopback PCM [Loopback PCM] Subdevices: 2/2 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Loopbacks!!!! WOOT! With this I will take it that the loopback and needed config files are correct, and have not posted them...

[icecast2-0] # The audio format to encode to, we're using mp3 here format = mp3 # The bit rate mode to use, the commented out lines are for a fixed bit # rate "constant bit rate" at 16 bits.

For mono scanner audio .1 is totally fine. quality = 0.1 # Takes the input and mixes it down to a mono output for the feed. channel = 1 # Cuts frequency response over 5kHz.

So the audio is not piped through some where????? I figured if it was a issue with audio, tags would come through with out the audio... ./rx.py --args 'rtl' -N 'LNA:19' -l http:192.168.0.28:8080 -S 2400000 -f 8xx.xxxxe6 -o 25000 -q 26 -T trunk.tsv -V -2 -U -W 127.0.0.1 2> stderrstream.2 Watching the http output I see data come in, TSBK count goes up, TG's appear etc... NO AUDIO :( on the feed, WITH tags.... :) Local audio comes out the speakers.... So audio is recovered and in good quality even for a Pi.. Any hints, clues? ?? ? I've tried a couple of different setups for the loopback with an .asound.rc in the /home/user, used loop1, hw:1,0, hw:1,1 etc. tried as 2 channel audio v. single channel audio in darkice... still silence is not golden.... :( Any hints on getting the loopback audio working?? ? ? ? ? I might try it on the laptop setup too to see if its a Pi thing... My hunch is the magic dark arts of the right ALSA name for where the audio is at is wrong in the darkice config....but I've tried everything I can think of Thanks.
