Re: Radios w/o a packet port

Indeed you adjust DINAH sound levels on Raspberry?OS using alsamixer.? Works fine.
As you note, the DINAH is just a USB sound card which can also generate PTT from a sound card GPIO pin.

Currently I'm using an inexpensive USB sound dongle (C-Media) with Direwolf. PTT is handled via the RTS pin on a serial port, which is run through a transistor circuit. The radio (Alinco DR-605T) doesn't have a packet port, but I made a cable, and everything works well. I adjust input and ouput levels via alsamixer in Linux.
I want to change to a different radio, which also doesn't have a packet port, but it would be easy to make a cable to adapt from the packet port on the DINAH to the radio. The DINAH is appealing because PTT is handled by the GPIO pin on the C-Media chip, so it saves a USB connection.? Is there anything that would prevent me from treating the Dinah the same as my other USB sound device and adjusting levels via alsamixer?
Thanks,
