USB Audio changes for USB slicekit

[nico]

Hi,

I have a USB slicekit 1V2. I developed an application around an old version of USB software. I need to find a bug so I try to revert to the original code but I no longer have it.
I downloaded the latest version of SW_USB_AUDIO which is 6.12.6 but this version is not working on the board that I have (erratic sound only at some sample rate, no sound at other). In the change log I found the following warning :

6.10.0
CHANGE: Support for version 2V0 of XK-USB-AUDIO-U8-2C and XP-SKC-U16 core boards and
XA-SK-USB-BLC and XA-SK-USB-ABC slices in app_usb_aud_xk_u8_2c and app_usb_aud_skc_u16_audio8 (previous board versions will not operate correctly without software modification)

Does anybody know what software modification I have to do to make this version work please ? I can't find it by myself.
Or does anybody know where I can download a previous version of the software that is compatible with my board ?

Thanks for your help,
Nicolas

I did find the old version of the code on XMOS website.

However my bug is there with the code version 6.6 unmodified : I have a glitch in the audio every 30s with my Mac (depending on the host, it can be 5 seconds).
It seems to be related to the clocking mechanisms, maybe the asynchronous part ... I have no idea where to find the cause of this annoying bug.
I have the same problem on two boards (both 1V2) so I guess that it is not a damaged board that causes the problem.

does anyone have encountered this problem ??

Some conclusions in case someone has the problem :
I found that version 6.11.4 is ok : no crack in the audio
6.6 works but has some cracks
6.12 is broken for USB slickest 1V2

I do not know what are the problems in those two versions ...

Did you try the latest version on the website? Im not expecting any versions to have audio artefacts though..
