Hello Lynn,

alsamixer -c 1

direwolf receives with this setup with no issues.? But when it tries to transmit, I see the red/pink/magenta [0H] line with the packet, but the SignaLink PTT light doesn't go red and the radio doesn't key up.? The Rx volume control on the SignaLink does affect the audio level of the receive packets.? But I find it strange that alsamixer only shows one control.

Signalink units have limited controls via alsamixer as some of their controls are ONLY available via hardware POTS on the front of the unit.? There is the F3 view to set playback levels and F4 view for microphone levels.?? The key setting here is that you must increase your playback levels higher and higher until the TX LED on the Signalink lights up.? Unless you can get that LED to light up, you aren't keying the radio.

Another test you can do is connect a set of headphones to the back of the Signalink and see if you can hear the transmitted audio you expect to be coming from Direwolf.? If you don't hear anything, you have some form of a configuration error.

I have a DINAH audio interface on a different Pi and alsamixer shows two controls, one for Speaker and one for Mic, and a 3rd for Auto Gain Control.? The Pi with the DINAH and direwolf has no trouble keying the transmitter, both the IC-706MKIIG or an Alinco DR-135 both using the same 6 pin mini-din connector

These use different sound chips and have different controls.? If I was to recommend it, I would recommend to use the DINAH over the Signalink.
