Hello David,
Ok, I will try that although I do not see much reason because the same radio
runs APRS excellently with my laptop comp, also running Debian 8. The
problem appears on desktop(s). But I will try.
After that, maybe you can do some live
playback of audio as heard from your souncard. Something like this
would work assuming you substitute in the correct sound card values and
connect your headphones to the appropreate soundcard output:
arecord -D plughw:CARD=Device,DEV=0 -t wav -f S16_LE -r 48000 -d 10 - | \
aplay -Dplughw:CARD=Device,DEV=0 -
Will try that too ...
Ps. I don't know why you oped to installed Debian 8.x aka.. Jessie but
as mainline security updates ended back on June 2018. It's only
receiving critical (but much slower) security updates through June
2020. Since you're starting with a new OS, why not start with something
that will have the longest life? That would be Debian Buster.
I know that Debian 8 is not 'young & fresh' but my computers are even older
and would hardly accept newer OSes. And some other machines I have (two
desktops and a laptop) still run Debian 8. So if I had different OSes on
different hardware, it would be even harder to locate the problem.
Hello Misko,
This is tangential to your original question, but I wanted to mention
that I have recently been through similar frustrations. I ended up
using a dedicated a Raspberry Pi 3 B+ to control my rig. It has low
power draw, multiple USB ports, and plenty of CPU to build and run
WSJT-X, tqsl, and the other software I use. But the main advantage is
that changes to my desktop machine don't affect my rig and vice-versa.
It runs Raspbian updated to Debian 10 (buster).
