Audio Crackling and Default Config unchangable on Windows(Main Branch)

[genusistimelord]

Using the Crates.io Version of Rodio the audio plays perfectly fine on Windows with

SpeakersBuilder::new()
            .default_device()
            .unwrap()
            .default_config()
            .unwrap();

however when using the Git repo version the audio is just pure crackling and popping noises.

the above example is using git = "https://github.com/RustAudio/rodio", rev = "a359d2a"

the is the working Example using the Crates.io Version

20260717-1552-33.1482909.mp4

Also I noticed in the Crates Version I can do

.try_buffer_duration(Duration::from_millis(1))
            .unwrap()
            .try_sample_rate(SampleRate::new(44100).expect("should never fail..."))
            .unwrap()

but if i try this in the main branch it panics saying unsupported device even though it worked before....

Please let me know if you have any questions.

Thanks for the report including sound clip. Rodio's crates.io release pins cpal 0.17, while master pins cpal 0.18. In between, buffering behavior changed as well as did the default sample rate from 44.1 to 48 kHz.

The reason for the panic is that 1 ms is not a supported configuration. In cpal 0.17, WASAPI reported buffer size as a wide-open range, so any buffer duration passed. In 0.18, WASAPI now correctly rejects what devices don't support. 1 ms is way too short, and that's the panic. If you want to see what's supported, run cpal's "enumerate" example.

The crackling is likely related, but I can't confirm from your report alone. Please report:

• Your device's actual default sample rate/format/buffer size (Windows Sound Control Panel > Advanced)
• Whether crackling happens with a plain .default_device().default_config() (no overrides) on the git version

@yara-blue a small debug helper that prints a device's default + negotiated stream config would make reports like this much faster to debug.

Good idea we should have some better debug tooling overall!

As soon as we landed all the new audio stream stuff I'll add that to the new output system (the now terrible named 'speakers').

Off-topic/planning
For now im focussing on landing the new const & fixed sources. Hope to get a load of PR's up before the end of the week though it will take a little to optimally integrate your rubato work rubato

Yes it did happen with just defaults and no changes. The reason why was not because of the Audio output but because I had too many players. So I redid the part of the code to remove the players down to just 3. As I noticed having to many players also cause this issue and the reason did have a bunch was due to documentation not pointing me to use the Control Mixer stuff for many different audio sounds to play at the same time. Though would be nice to have a mixer where i can Get access to the individual sounds or music playing in it to adjust their Volume or Amplify them when needed. Though I did start to have issues using the mixer with the Audio Done stuff not returning the events due to a previous issue with Mixer stuff which I found the fix and implemented it in my own Done type. Do we have a function that can list all the supported stuff per audio device? I saw something that output an audio device with its current Settings but not what is supported?.

The having to many player issues seems to show some regression in cpal or Rodio. As I think it degraded the processing of the audio which restricted how many players on the machine you could possibly have.

Yes, cpal has this. To enumerate everything a device can do, use Device::supported_input_configs() / supported_output_configs(). As I said, check out cpal's enumerate example.
