Re: Round-trip latency of USB Audio is not stable
Variability across start and stop occurs in the input path, ie device to host. When streaming stops, buffer of the input path (called aud_to_host_fifo in the code) overflows. There is a mechanism in there to reset the buffer to half full and stay like that until streaming resumes. It does that on by...

Re: xcore-audio hi-res 2 : 32bits on a Macbook with macOS High Sierra
It was just an idea to test if there is something about the device's descriptor that macOS doesn't like

Re: xcore-audio hi-res 2 : 32bits on a Macbook with macOS High Sierra
The process is to run the xConfigurator script to generate a binary. This needs to be programmed in the SPI flash of your xCORE-AUDIO board.

Re: xcore-audio hi-res 2 : 32bits on a Macbook with macOS High Sierra
Resolution is set to 32bit in the xCORE-AUDIO's internal firmware.
What I meant was reducing the device to 48kHz using SAMPLE_RATE_BITMAP of the .cfg file. Then check if macOS still fails to offer a 32bit option.

Re: xcore-audio hi-res 2 : 32bits on a Macbook with macOS High Sierra
Did you have access to documentation? I think it's a plain text file distributed alongside xConfigurator.

Re: xcore-audio hi-res 2 : 32bits on a Macbook with macOS High Sierra
Do you have access to xConfigurator, the configuration utility for your xCORE-AUDIO board? It's on the xCORE-AUDIO page on XMOS.com under xCORE-AUDIO configuration utility.

Re: xcore-audio hi-res 2 : 32bits on a Macbook with macOS High Sierra
Sorry, I meant restricting sample rate using the HRA configuration. Do you have access to that?

Re: xcore-audio hi-res 2 : 32bits on a Macbook with macOS High Sierra
There must be something about that descriptor that macOS High Sierra doesn't like. I have an XMOS device with a similar configuration (16/24/32bit) that enumerates fine and allows selecting 32bit in Audio MIDI Setup. If you restrict the device to 48kHz by setting MAX_FREQ to 48000 does Audio MIDI Se...

Re: How to resolve a CDTDebugModelPresentation.12=signal
The CDTDebugModelPresentation message, I guess. It looks like the double clicking happens later and might be a consequence of the CDTDebugModelPresentation message.

Re: How to resolve a CDTDebugModelPresentation.12=signal
I ask to establish if this could be an xgdb issue or an xTIMEcomposer (Eclipse) issue
