semi success but tx starts in mono for stereo usb sound card

by drew Roberts

Well, for testing purposes, I have set up 2 Pis on a local lan. Transmitting PI has usb sound card and openob uses alsa invoked like this: /usr/local/bin/openob 192.168.86.149 test-tx-node test-link tx -a alsa -d hw:1 192.168.86.149 aplay -l gives: card 1: CODEC [USB AUDIO CODEC], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 Receiving Pi uses onboard sound card and openob uses jack invoked like this: /usr/local/bin/openob 192.168.86.149 test-rx-node test-link rx -a jack -jn openob -aj -jp jack_mixer:ICh2 It is also running jack-mixer and a few other toys. After hooking things up as desired in qjackctl, I see the mono audio in jack-mixer and hear it in my headphones plugged into the Pi's soundcard. Any thoughts on how to track down the mono issue? all the best, drew -- Enjoy the *Paradise Island Cam* playing *Bahamian Or Nuttin* - https://www.paradiseislandcam.com/

Re: semi success but tx starts in mono for stereo usb sound card

by Lorne Tyndale

Just as an FYI, I've run into a quite a few stereo USB sound cards that - even though they are stereo - only get recognized as mono on the input / record side by ALSA. Sometimes they can be forced to stereo mode by tweaking .asoundrc, and sometimes that doesn't even work. In my experience USB sound cards are a hit and miss to whether they actually get seen as stereo inputs.

James... Doing the actual machine with the hat this morning. Found an error in the docs you sent which I overrode without noting.

Re: Raspbian Stretch?

by drew Roberts

James, thanks so much for you help. I now have audio flowing. Newly installed openob and openvpn on the send side (raspberry pi).... Old openob and openvpn on the receive side (server/nook side)... USB sound card on pi for now. I see audio passing through the meters on the nook. (Some messages make me think it may be mono and not stereo at this point, but I am too burned out right now to troubleshoot... Thanks again. all the best, drew On Wed, Nov 20, 2019 at 3:12 PM james(a)digital-light.co.uk < james(a)digital-light.co.uk> wrote: > Hi Drew, > > There are a few dependencies that have moved on in terms of version > numbers, but it does work. > > I managed to get it all working on stretch and documented the process some > time back when I was tinkering with openob-gui, looking at my notes: > > sudo apt-get install python-gst-1.0 gstreamer1.0-alsa libgstreamer1.0-0 gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools > > sudo apt-get install gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly > > sudo apt-get install python3-pip > > pip3 install openob > > Should get you through it.

Raspbian Stretch?

by drew Roberts

OK, does anyone have openob running on raspbian stretch? Any gotchas? I am having issues. I would be quite happy setting up 2 Pis with openob on a lan as a first cut. Do I need to ditch stretch and go back to jessie on these machines or can we get openob running fine on stretch? I don't really want to be doing this. We had a nice setup all tested out. A Nook next to a rivendell server. The Nook running ubuntu and openob. The remote and had a pi running openob and a "hat?" soundcard. (Can't put my hands on the link to it now.) A little mixer, a mic, a laptop. The remote person could connect to the "studio", control the nook and rdairplay and run a whole remote show from the field without a boardop in studio. openvpn between the pi and the nook with openob over the vpn link. We haven't used it in forever. Now have a need again and openvpn and openob seem to be missing from the remote pi. (Plus the Nook seems to be rebooting about every 10 minutes for some reason we have not been able to track down yet. Ouch. So, I am trying to get the pi end working again (with a new pi at first) and then work on the nook (or a replacement) end... I know this is a bit long winded, but the actual setup was quite sweet and I thought it might inspire someone. -- Enjoy the *Paradise Island Cam* playing *Bahamian Or Nuttin* - https://www.paradiseislandcam.com/
