@tsangyoujun any chance we can upgrade via OSX?
You can attempt an upgrade via OS X. However it didn’t work on my end - The OS X upgrade software isn’t well written, according to @Terry .

From the spec, it was said tone board can support pcm 32bit 768khz, why the new firmware only supports 32bit 384khz, what I missed here?
The original spec was in error, we have since corrected it on https://www.khadas.com/tone-specs as well.

Hi youjun,
Why khadas cannot support 768khz? Is that a limitation from hardware, oscillator?
@Terry can explain better than I can.
Hi @tsangyoujun
Is there by chance planned any upgrade to newer version of USB drivers for example 4.xx series?

Is there any reason for using the 4.1 Eval version to update the board? Is it not enough the TUSBAudioDfu.exe file installed with the v2.24 drivers?
This would be fantastic since there are active firmware made
