I’ve just moved to ASL3 from HamVoip, by golly that was an easier setup process!
As part of the move, I wanted to move my two RF nodes onto one server. Utilising two CM108 based sound cards.
I’m facing issues when both nodes go into transmit where only one radio transmits audio.
I’ve scoured the rpt.conf file along with the user manual to try and get to the bottom of it, without any luck.
For now I’ve moved one node to another Pi. Any ideas please?
Thanks!
Are you trying to set both radios up on the same Raspberry Pi? If so, is that a Raspberry Pi 4 or 5?
There are known problems with multiples of the same type of device connecting to these hosts, nothing at all to do with ASL. I would recommend using a PC instead of a Pi for a multi-radio setup. There are USB hubs with a very specific chip set that can be used to get around this problem, but I don't remember what that is.
Yes, That was what I was attempting with a Pi 4. If you do remember what the USB hub you are thinkig of, please let me know!
Thanks!
i was just reading a report stating the issue was a linux kernel problem and to use a RPi 3B with multiple interfaces until further notice.
however, i believe it's been long enough since that report for many newer kernel versions to arrive, especially if you set up an ASL3 Appliance.
specifically what to do to try to make a go of it with ASL3, i don't know, but perhaps this thread will elicit some assistance from those intrepid enough to try again?
Multiple audio adapters are not, in general, a problem. Where you got into problems on a Pi 4 was power bus limitations if whatever devices you were using drew “too much” power. A Pi 5 is perfectly fine with multiple adapters - I have them.
It is actually not a problem with running out of power, although that is sometimes a consideration for other hardware. There was a real issue, mostly with raspberry Pi 4 boards, and I think some very early rPi5’s, wherein multiples of any kind of USB device, whether it was audio, storage, etc. Had unexpected results. I definitely ran into that with both ASL3 and HamVoIP on more than one rPi4 board, yet the exact configuration (literally just pulling the MicroSD card out) worked perfectly on an older rPi3 board.
