imxrt1010 usb_dev_audio_speaker_bm example

[SergioNpl]

Hi!

Configuration Descriptor in example has the following values:

number of bytes occupied by one audio subslot - 2

number of effectively used bits from the available bits in an audio subslot - 16

Any other values not work.(for example: bSubslotSize=2 bBitResolution=8;)

There are no error messages during initialization (win10),

but playback is not going on. Some players report: "Unrecoverable playback error: Unsupported stream".

I have studied the UAC2.0 standard, but I have not found other places where it is necessary to specify the bit depth of the samples.

Can someone help me ?

Hi @SergioNpl ,

Which SDK version you are using? So far the latest supports RT1010 is ver 2.14.0 , but I could not find something like bBitResolution in the latest version. Please kindly clarify.

Have a great day,
Kan
