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