Topic: Noise burst with HDSP 9632 / Windows 10 v1809
I'm dealing with an unexpected issue with my HDSP 9632 since last Windows 10 update to v1809.
Computer: ARBOR FPC-7300 (a fanless box PC with one PCI slot)
Processor: Intel Core2 Duo CPU P8600 @2.40 GHz
RAM: 4 Gbyte
Windows 10 Pro v1809 (since 27-12-2018)
RME HDSP 9632 in PCI Slot
HDSP driver: version 4.26
HDSP firmware: 155
Connected to RME ADI-2 Pro through XLR AES/EBU
Foobar2000 audio player, used with WASAPI driver in event mode.
Windows audio interface set in exclusive mode
Up to recently, everything worked fine at any bitrate from 44.1 to 192 kHz in both 16-bit and 24-bit resolutions.
But now I get a burst noise instead of music when playing anything else but a 44.1 kHz / 16-bit audio file.
The ADI-2 still recognizes the bitrate and resolution of the signal transmitted by the HDSP, but the sound is broken.
As my PC has a dual boot installation of Windows 10 and Windows XP, It is worth mentioning that everything still work fine under the XP environment (using the same 4.26 version of HDSP 9632 driver).
This means that the PCI board and the ADI-2 are ok, and a firmware/software issue must be considered.
So I suspect something wrong with the last Windows 10 update to v1809 ...
I've tried to remove anr re-installed the PCI card to force Windows to detect the HDSP board again, re-install the HDSP driver, tried other audio players, but always with the same result.
I really don't know what to do next and I would appreciate some assistance.
