DirectStream Snr. DAC and Windows 11


I’m planning to move from Windows 10 → Windows 11 soon and just have a few quick questions.

  1. Any compatibility issues between Windows 11 and the Directstream Snr. DAC?
  2. Can I use the same driver found on the USB driver download page for Windows 11?

I upgraded from windows 10 to windows 11 quite a while ago and have not had any issues with the PSA drivers.


Ok. That’s great to hear. Thanks for the quick reply.

Just in case you’re using a Matrix Audio X-SPDIF 2 between Windows and your DS DAC, there’s an update to the ASIO driver (for Windows) available from the Matrix Audio downloads page. It appears to be just a minor update ‘for Windows 11’. I’m using it on my Windows 11 without issue. :+1:

Woah! Looks like we’ve had a forum clean up! RIP ‘Matrix X-SPDIF 2’ topic. :roll_eyes:

Moving right along, Matrix Audio released another update for the (Windows) ASIO driver on August 19, 2022 (version 5.45.0).

I’ve installed on my Windows 11 and it appears to be working OK.

Just mentioning a possible ‘gotcha’. If, like me, you run the X-SPDIF 2 with an external LPS and you’ve disabled the power line on the USB output at the PC end, you may need to power-cycle the Matrix for it to re-establish a connection with the PC.

You’ll probably also need to reset the Matrix’s device properties via the ‘Sound’ Control Panel applet (mmsys.cpl).

Enjoy (or not)! :yum:

Edit: Oops! It appears I didn’t look thoroughly enough. The ‘Matrix X-SPDIF 2’ topic is still alive and well! I’ll cross-post this comment to there. :wink:


For those who are interested in such things, Matrix Audio released ASIO driver for Windows, version 5.50.0 on September 8 (up from 5.45.0) for use with the X-SPDIF 2. Looking at the Change Log, it appears to be coincidental with Microsoft’s Windows 11 feature update 22H2. From the Change Log…

Matrix Audio USB Audio 2.0 Class Driver for Windows
Revision History
V5.50.0 (September 8, 2022)

  • New: support for Windows 11 (22H2) x64
  • New: support for Windows 11 (22H2) arm64
  • Fix: USB IN buffer count was limited to 16 buffers, this lead to not enough buffers for high ASIO buffers sizes (e.g. 48kHz and 1024 samples)
  • Fix: preferred ASIO buffer size are not restored after driver unload/load
  • Fix: MIDI functions could become a ASIO device (e.g. if the device has dedicated Audio and MIDI functions)
  • Chg: documentation

Look out for the usual gotchas.

  1. If it’s externally powered, you’ll probably need to power-recycle the X-SPDIF 2 after the update, and
  2. You’ll need to reset your preferred sound device properties in the ‘Sound’ Control Panel applet (mmsys.cpl).
