PortAudio error when trying to open audio device exclusively #1

Open RipperFox opened 3 years ago

RipperFox commented 3 years ago

OS: Windows 10 20H2 64bit Soundcards: OnBoard Realtek ALC1200 Codec (defaults to 24 Bit(!)/48kHz) / registered VAC 4.65 / IC 7300

When running your version 0.87 PA reports error -9997 on all my audio devices but the IC 7300, e.g.:

Start request for CAP stream:Line 3 (Virtual Audio Cable)
Starting CAP stream:Line 3 (Virtual Audio Cable) [7]
create resampler 7 real 48000 req 44100
0.918750  44100.000000  48000.000000
err:-9997 device:7 PAdev:20 samprate: 48000.000000
cannot open capture stream for device:<Line 3 (Virtual Audio Cable)> -9997
CAP: cannot open device: Line 3 (Virtual Audio Cable)

I got rid of error -9997 by removing the paWinWasapiExclusive flag from PaWasapiStreamInfo. Error -9997 reads "wrong samplerate", but I think it might something else.

Is "Exclusive mode" really necessary? This mode is designed for e.g. outputting native Dolby Digital, DTS, etc and goes around Windows' internal resampler/mixer..

I still got error -9998 (wrong number of channels?) on playback:

Start request for PB stream:Lautsprecher (Realtek(R) Audio)
Starting PB stream:Lautsprecher (Realtek(R) Audio) [3]
create resampler 3 real 48000 req 44100
1.088435  48000.000000  44100.000000
Playback : err:-9998 device:3 PAdev:16 samprate: 48000.000000 chans:2
Playback started sucessfully

..but playback actually works anyway!

Thanks for your great work!

PS: You could vastly reduce compile time of hsmodem: https://helgeklein.com/blog/2019/12/enabling-multi-processor-parallel-builds-in-visual-studio/ Enabling this reduces build time from ~18 to <3 seconds for me :)

Tested with version 0.87 from https://dj0abr.de/german/technik/sat/modem/images.htm

Still unable to open Audio devices in exclusive mode:

maybe the problem could be solved if hs modem would use 48000 sample rate?!? i have sett all my soundcards (and virtual cables) to 48000 ... and also get error -9997 why do i use 48000 ?? cause sdr console uses 48000
