sound devices, Pat-Gensio, Rasp 4 and Ubuntu

[Michael Lussier]

I'm running Ubuntu 22.10 on Raspberry Pi. This boots off of SSD 1 TB drive.

I have been experimenting with PatGensio for the last week. a few things have come to light and I'm curious if anyone else has seen this.

1. Signalink shows up as a playback only device in alsamixer  on the pi. There is no microphone option.

I have two signalinks and then both exihibit the same results.

 USB-Audio - USB AUDIO  CODEC   

BurrBrown from Texas Instruments USB AUDIO  CODEC at usb-0000:01:00.0-1.2.3

2. I have a DRA 50 USB-Audio - USB PnP Sound Device                                               │                 C-Media Electronics Inc. USB PnP Sound Device at usb-0000:01:00.0-1.2.4

why does the signalink show as a playback only device ?

is there any way to using the DRA50 and  utilize CM108 to keyup a radio ?

It only allows volume control on the play, but not on the record. It
still can record and playback.

You can use "aplay -L" or "arecord -L" to see the sound cards devices
available. Or "gsound -L' if you installed gensio.

I have a DRA-50, and you can use pat-gensio with it. I use rigctld to
talk to the CM108:

rigctld -m 1022 -r /dev/ttyUSB0 -s 4800 -P CM108 -p /dev/hidraw1

and my gensio line is:

"gensio": "afskmdm(debug=0x18,tx-predelay=500,key=\"tcp,localhost,4532\",keyon=\"T
1\\n\",keyoff=\"T 0\\n\"),sound(48000-1-float),plughw:1,0"

The "key" option tells it to make a TCP connection to rigctld, keyon
and keyoff send those strings to key the transmitter.

Oops, I forgot to say that I have an TM-V71A. You will need to modify
this to match your radio, or use "dummy" if you don't have a
connection to your radio. Like:

rigctld -m 1 -P CM108 -p /dev/hidraw1

Corey,

Thanks for the push in the right direction. nothing happends when I initiate a connect to the gateway. and pat times out.

I'm using rigctld -m 1 -P CM108 -p /dev/hidraw3

I went into Alsa and turned up the mic and the output and stored the information.

In pat I have made the changes . 3,0 is my device
