RPi 3B+ w/ Buster, Alsa, Signalink USB
|
Anyone have any luck with this configuration? Alsamixer cannot see the microphone input of the Signalink USB (or another USB sound card on hand). The audio level is very marginal on the low side with the RX knob turned all the way up.
It looks like a driver issue to me. I tested the Signalink USB on a recent Linux Mint version with the same symptom. Pulse Audio on the Mint system seems to be able to see and control the microphone, but I would rather not burden an RPi with Pulse if at all possible. Thanks, Mitch, AB4MW

I have a 4 that I just configured, and didn’t have any trouble with ALSA and a signalink. I did have to go into alsamixer and set the levels first, then fldigi and such seemed to work ok.

That's the issue. Alsamixer doesn't recognize that there is even any microphone to adjust. It's so low that even FLDIGI's waterfall gain control won't bring it up enough for my satisfaction. I was surprised when this happened in Mint on an x86_64 machine though.

So nobody has RPi 3B+/Buster working with a Signalink??

I missed that massage, I have both RPi3 and RPi4 on buster with Signalink. If you don't have audio - try to plug the Signalink to your RPi *AFTER* your RPi boot I found that when you plug everything and then power things up - you won't have audio I/O

Yaniv, That's quite interesting. Thank you. And I will try that.

Hi,
I have a Raspberry Pi 4 with a Signalink. The OS is Ubuntu 22.04 and it detects the external sound card. But with alsamixer I coudn't find the line in (microphone). Where I must change the hardware driver or audio config to the line signal from external device SLUB. Anyone has an idea?
