Issue with external audio device

[marcdsdavid]

Not sure exactly what is the cause of this, but when I run the cli tool the audio is glitched (high pitched) and also comes out of all the outputs of my device.

Can you try to clone this repo, change the BLOCK_SIZE to 64 (Line 34 at main.rs) and run with cargo run --release?
Also try to change the content of test.glicol to o: sin 440. Hopefully you can get a pure sine tone.

[marcdsdavid]

Just tried your recommended changes but I still get a very high pitched tone that gets sent to all the software playback channels of my soundcard (RME Babyface Pro fs) - I also tried a sampling rate of 44.1kHz but it gives me the same result.

It works completely fine if I set my default output device to my Macbook Pro speakers.

here is what I did to get the result showed in the video:

• Cloned the repo, had to run cargo update because of this error (error: failed to run custom build command for coreaudio-sys v0.2.11)
• Changed the BLOCK_SIZE to 64 as you mentioned

and ran cargo run --release test.glicol

right. can you try to clone this repo: https://github.com/RustAudio/cpal/

and run cargo run --release --example beep

glicol cli depends on cpal to access the audio interface

[marcdsdavid]

cpal gives me a nice 440Hz tone. It sounds distorted on the recording probably because it still sends the audio to some extra software outputs when it should just go to AN 1/2 and I assume the screen recorder captures them all.

thanks for the info. I will look into it with my Focusrite audio interface when I get home. You may try the first method one more time if possible but change the block size to 32.

[marcdsdavid]

Thanks! I tried with a block size of 32 and get the same result as using any other block size (instead of 440Hz I get 3080Hz tone)
