Audio Issue
Hello, I keep getting this error when I try to start up DSD. I was wondering if I could be given any guidance as to a solution. I am running this on a Ubuntu 18 version of Linux on a VM. I get this error no matter what audio device I choose.

I also encounter the same issue. I didn't find " /dev/audio " in my linux (ubuntu 14.04).

Base on your audio port listing. You should get it going with dsd -i pa:4 -o pa:4
I also encounter the same issue. I didn't find " /dev/audio " in my linux (ubuntu 14.04).
/dev/audio no longer available on most of today's Linux. I got my dsd going with the following padsp dsd -i /dev/dsp
I'm encountering similar errors any time a sound device is specified. This appears to be a somewhat common issue with programs that use portaudio although the solutions are admittedly a bit over my head. Currently I am unable to use this with anything besides Gqrx and an rtl-sdr which does not have the best reception compared to the Yaesu.
