Cabled to Line In. OK Dreams shows signs of working in AM mode. Promising. Now trying ways of patching audio between Gqrx and Dream. Currently trying QjackCtl. Still see no audio from .wav files. Dream still has a problem in that with use, the GUI falls to tray where it will not come out (like 3 above). The only solution is to uninstall, delete dream.ini and reinstall. Other minor problems plus those in 4) above. Good. The first signs of working. Garie Miller gmill777@protonmail.com

I have installed "Pavucontrol" thinking I might help diagnose the no audio problem. Under the "Playback" tab Pavucontrol finds "GQRX:Audio output on" and "Dream Receiver:Audio output on". Under the "Recording" tab it finds "Dream Receiver:Signal input from". But no audio output from Dream yet per what I have experimented. Something like Pavucontrol may be necessary to insure audio is piped to Dream, in this case from GQRX, but I do not know for sure. Garie Miller gmill777@protonmail.com

Here are my results so far. 1) No audio out. In my installation I have both HDMI and analog stereo. Both seem to be detected correctly via "Alsa" in the menu. Strangely both are also listed again as audio inputs. Probably incorrect behavior. I can see Dream is decoding .wav files but no sound. 2)Running in terminal. The 48000 1280 1 I noted above are definitely parameters being passed probably to pulseaudio. Notice the 4th, probably nullptr is indeterminate. See attachment where I changed the rate...

Well I have some good news (I think). Using the src from tag 2.3.0, plus commenting out some lines as described above, Dream now builds, installs and runs in Debian. It mostly works except there is still no audio out, at least so far. There are many warnings during build that I did not look at closely. I attach one of them which was in the drm_pulseaudio file (line 257) although it may have nothing to do with the problem. You may watch what I am doing at Gitlab Salsa project 7803 Branch 2.3.0.

What is the "48000 1280 1"? Are those the parameters from: pa_stream_set_buffer_attr(pa_s, &pa_attr, pa_stream_success_cb, nullptr)? If so, where is nullptr? Garie Miller gmill777@protonmail.com

Say for what its worth (which probably isn't much), I just noticed that the Pulse code line 2663 above is similar to Dream file sound/drm_pulseaudio.cpp line 479. See attached. This may be where the parameters get passed to Pulse. Suspect the problem is around here. Garie Miller gmill777@protonmail.com

Yes I get the identical output running in terminal. Dream builds in Ubuntu/Mint 20 provided some code is commented out regarding an fatal compiler "illegal cast" error. I built locally using debmake/debuild preparing for Debian submission. It dies during run as above. I have no debugging skills but maybe this will help. The "pulse/stream.c" line 2663 is from Dependency libpulse-dev, eventually /sources/pulseaudio/*/src/pulse/stream.c. If you search the Dream code for "CSoundCardSelMenu::OnSoundOutDeviceChanged"...
