Topic: Madiface XT vs Zbook vs Sequoia LABs
I'm attempting to qualify a HP Zbook 15 G5 for large track count live recording with Madiface XT via USB 3.
It took me a looooong time to find the right combo of UEFI/Windows settings to achieve reliable low DPC's on the ZBook. Often, "not tweaking" led to the best outcome. I have carefully documented my steps and imaged the system drive regularly along the way.
One mystery eludes me though.
I cannot get Sequoia to record continuously without LABs (Lost ASIO Buffers) every 5 or so minutes, *except* in the following circumstance:
- I enable 1 stereo WDM device (Phones) in the XT driver, and make that the default Windows audio device.
- I play back an audio file with Windows Media Player while doing the Sequoia test recording (same sample rate).
If I do both those things - Sequoia is LAB free. If I don't, there are LABs every few minutes. It's completely unintuitive, but I'm hoping this points to something as a root cause?
Just FYI, there is no combination of the settings in UEFI / Windows / RME driver / Sequoia I have not tried, documented and then rolled back if no improvement.
The reason I stumbled upon the WDM playback "fix" is I was intending to take a Win Performance Recorder trace and examine for an audio glitch in Media eXperience Analyzer.
Hoping super knowledgeable people like @MC @Timur Born might have some ideas.
Thanks in hope!
