Phil, When I look through the logs you attached, on the Opus receiver it claims it is receiving stereo audio: 2020-06-24 15:52:45,360 - openob.node.test-rx-node.link.test-link.rx - INFO - Receiving stereo audio transmission I also see in the transmission it claims it is sending mono: 2020-06-24 13:51:51,228 - openob.node.test-tx-node.link.test-link.tx - INFO - Started mono audio transmission Is it possible that you are actually sending stereo and the transmission notice claiming to be mono is just incorrect? Also, I know it takes up more cpu cycles, but have you tried running your audio through Jack on the transmission end?

I communicated with you all on the list to try to get by the “My Mono Problem” I was having and eventually gave up. I'm back now trying again to get this to work for a community radio station (KBOO) backup STL that’s really needed. My configuration is: Raspberry Pi3B+, Behringer UCA202, OB V4.0.3 running under the current version of Raspberry Pi OS (32-bit) Lite, Kernel Version 4.19. This time I have had a bit more success in that I have been able to get a stereo link established by running the transmitter in PCM mode. However, when I try to use OPUS encoding the link is established but it is again in mono. > > > > How can I get a stereo link using OPUS encoding?

Re: OB and Behringer UCA202

by Lorne Tyndale

Phil, It sounds like for some reason Opus isn't picking up both inputs on your sound card. I don't know if this will help, but have you tried creating a ~/.asoundrc file specifying the channels? Something like the following: pcm.!default { type plug slave { pcm "hw:1" channels 2 format S16_LE rate 48000 } } Also, my reasoning for trying it with Jack is that sometimes Jack will pick up both inputs on a USB sound card whereas straight ALSA won't. I know that Jack does eat up CPU cycles, but if it'll work with Jack but you can't make it work with straight ALSA, then this might be a solution, at least for testing. Lorne > > Hi Lorne, > > Thanks for getting back to me. > > > > When I use opus, the transmitter is sending mono. The receiver is decoding stereo but the audio is truly mono as removing the left input to the transmitter causes both channels to drop. Also, there is only one channel shown in the level displays. This is shown in the first two logs. In the third and fourth logs, using pcm, the transmitter is showing a stereo channel and the receiver is decoding two channels. This is also seen in the two channels reported by both ends in the level displays. > > > > I do not want to increase complexity and decrease cpu overhead by adding Jack just to make this link work correctly. This will be a critical STL link and it has to be robust. The same applies to pcm, it requires too high of a bitrate and will drop packets when the network gets congested. Opus is essential to reduce the rate to keep packet loss as low as possible. > > > > I have noticed that when I plug one of the Behringer UCA202s into my windows 10 PC that it records in mono as well.

I communicated with you all on the list to try to get by the “My Mono Problem” I was having and eventually gave up. I'm back now trying again to get this to work for a community radio station (KBOO) backup STL that’s really needed. My configuration is: Raspberry Pi3B+, Behringer UCA202, OB V4.0.3 running under the current version of Raspberry Pi OS (32-bit) Lite, Kernel Version 4.19. This time I have had a bit more success in that I have been able to get a stereo link established by running the transmitter in PCM mode.

Shut down function

by Aurélien Lorence

Hello, I'm currently working on a project which integrates OpenOB in a python program. I have a "start" button to run a link in a thread. Is there any way to stop the link without exiting the whole program. I tried to implement this in the code, but the node keeps restarting when shut down. Any clue ? *Aurélien Lorence* *Technicien* -- <http://www.c-lab.fr/>*Place du Recteur Henri Le Moal* | *35043 Rennes Cedex* Tel: *02 99 14 19 64 *| www.c-lab.fr *| 88.4 FM | *Newsletter #11 <https://bit.ly/2K83S0u> <https://twitter.com/RadioClab> <https://www.facebook.com/RadioClab/> <https://www.instagram.com/radioclab/> * Afin de contribuer au respect de l'environnement, merci de n'imprimer ce courriel que si nécessaire.*

OB and Behringer UCA202

by Phil Biehl

Hello All, Late last year I spent a lot of time trying to get OB working on a pair of Raspberry Pi3s. I communicated with you all on the list to try to get by the “My Mono Problem” I was having and eventually gave up. I'm back now trying again to get this to work for a community radio station (KBOO) backup STL that’s really needed. My configuration is: Raspberry Pi3B+, Behringer UCA202, OB V4.0.3 running under the current version of Raspberry Pi OS (32-bit) Lite, Kernel Version 4.19. This time I have had a bit more success in that I have been able to get a stereo link established by running the transmitter in PCM mode. However, when I try to use OPUS encoding the link is established but it is again in mono. How can I get a stereo link using OPUS encoding? Help please! Thanks, Phil Here's terminal output for PCM Transmitter side: pi@OpenOB-TX:~ $ openob -v 192.168.0.162 test-tx-node test-link tx 192.168.0.162 -d hw:1 -a alsa -r 48000 -j 1000 -e pcm 2020-06-24 13:47:48,561 -
