Hello,

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,

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.
