kiwiclientd.py sound trouble

[hamav8tor]

Having some trouble getting kiwiclientd.py to play to any sound devices. No sound output at all. Errors shown below. This is on a Mac Mini with the latest master. I can connect/record with kiwirecorder.py and can successfully hear the expected audio in the wav files, so the KiwiSDR connection is fine.

I did not write kiwiclientd. Let's see if the author @rikvanriel has any suggestions. What versions of OS X?

[rikvanriel]

On line 69 of kiwiclientd.py we have this bit of code:

for i in range(0,10): try: self._player = speaker.player(samplerate=rate, blocksize=4096) self._player.__enter__() break except Exception as ex: print("speaker.player failed with ", ex) time.sleep(0.1) pass

Do things work if you remove the ", blocksize=4096" bit, so that line looks like this:

self._player = speaker.player(samplerate=rate, blocksize=4096)

If everything works without a blocksize parameter, great. If you get audio skips when not specifying a blocksize at all, can you try it with blocksize=512?

Once we know what works on your system, we can adjust the code to get it to just work automatically on OS X again, too.

Okay! Removing the blocksize parameter worked for me here. Older MacBook Pro running OS X 10.15.7 (Catalina, also old). I had to remove --snddev="Display Audio" and use the default sound out device since I don't know the proper device names that the soundcard module expects ("Display Audio" didn't work for me).

Thanks for the help! It works with no blocksize parameter and with a blocksize of 512. I am getting audio skips with both. Not sure how serious it is yet because I am listening to static at the moment, primarily. Once I hear some voice traffic I'll have a better idea of how bad it is. It may not be that bad.

[rikvanriel]

I think we may have to make kiwiclientd multithreaded to not get audio dropouts with a smaller buffer.

I can take a stab at that later this week.

Filed a pull request with a fix for the immediate issue.

I checked further and not 100% sure if I am getting audio dropouts...hearing what I think are some micro-dropouts but could use another pair of ears to check:

Sample sound file - HF radio via KiwiSDR

I don't have my good headphones here (I'm on vacation) but it does sound like some drops and thumping going on. In fact it's reminiscent of the Chrome audio bug (pre-v90) that we had a while back.
