Hi Robbo,
No, I did not. I have OS5.2A for the Audya 76 & for the Audya 5. I have made those available long ago
HERE. Just look for it on those pages.
I do NOT have it for the Audya 4 module, so I cannot help those as yet. This issue is important to me, so believe me I'll make available to ALL as soon as I receive ANYTHING whatsoever!
Cheers,
Henni
