Re: [chuck-users] chuck and apple airpods?

Hello Ge, I've also had trouble with Apogee Jam/Jam+ and Apogee ONE devices not initializing correctly, I wonder if the fixes in 1.5 might also work for those? Please let us know if we might help test before the upcoming release! Cheers, michael On Thu, Apr 13, 2023 at 1:34 PM Scott Smallwood wrote:

Hi Scott!!

Indeed, this has been an gnarly and gnawing issue -- Apple AirPods (and a number of other Bluetooth headphones) show up in macOS as its own audio input device and supports only one sample rate (24K in the case of AirPods). ChucK, like most full-duplex audio software, requires matching sample rates for audio input and output. By default, it would try to initialize with a sample rate of 44.1K or 48K and would fail initialization due to the rate mismatch with the AirPods.

short-term workarounds: 1) in System Settings -> Sound, under "Input", select something other than the AirPods as the default input audio device (this is relevant to command line chuck) 2) in miniAudicle or command-line chuck, choose a different device for the audio input that's not the AirPods. (e.g., in miniAudicle, select a different Audio input in Preferences; with command-line chuck, can use the --probe flag to see available devices with input channels and then use --adc:DEVICENUMBER to select a specific input device)

Long-term solution: The good news is that we just addressed this very issue in the code literally yesterday (ChucK now has additional logic when initializing default audio devices, and will automatically try to match with a different input devices when needed; this logic was added specifically to address the AirPods/bluetooth problem). This fix will be part of the next release (btw ChucK 1.5 will be a big release, with a truckload/chuckload of new features, bug fixes, and probably new bugs)! The release is imminent; likely within the week.

Hope you are well and rock on, Ge!

Hey ChucKians!

So, I've had my first issue with an audio device on Mac silicon and ChucK: for some reason, when I am using my Apple Airpods, ChucK will not send audio to them, complaining that it can't get a sample rate:

[chuck]: (CoreAudio) no supported sample rates found for device (0)...

Anyone have ideas?
