Topic: MF II sporadic screeching noise
Dear RME team and community,
thank you for providing such a useful resource with this forum, and apologies for this long post.
I'm running an Multiface II that I recently got in used condition.
a PCI-Card Rev. 1.9 in a native PCI slot without PCIe adapter
no power supply for the MF II
I have just run hdsp_wdm_fut and it says Firmware v55
Windows 10 Pro 20H2
HP z230 Workstation Tower with Xeon E3-1245 v3 CPU and 400W PSU
I'm using the motherboard's internal GPU
One PCIe peripheral, a 2-Port USB 3.0 card.
Let me preface this by saying that I'm running RME's driver v4.29 and have not
yet updated the driver because I wanted to post here first.
Sporadically when playing Windows WDM audio, for example through Winamp or watching a livestream, the audio cuts off, a loud screeching noise (similar to a cut up pulse wave) can be heard and lots (all?) OVR indicators in TotalMix FX turn on.
This can happen at any time, I experienced it running music through Winamp a few minutes after boot, then again a day later after watching a video livestream in Firefox for about four hours.
It seems that when it happens, Windows can't detect the WDM device any longer, because Winamp showed an error window with "Error creating DirectSound buffer. Error code: 88780096" at that point.
When it occured during the live stream, the video stopped.
I can make it run again without rebooting by first clicking the "I/O box - Disconnect" checkbox in the DSP settings, then deactivating the checkbox again.
I had been using a Multiface (1st version) with that same v1.9 PCI card without any issues for over a year. I didn't change any settings or drivers when changing from the MF I to the MF II, just powered down the PC, switched the host cable from MF I to MF II and booted up again. I then acticated the "I/O box - Multiface II Connected" checkbox in the DSP settings.
The MF II is always detected when booting into Windows, the red host light is on, then the two yellow MIDI lights turn on, then all lights turn off.
I have not yet tested extended DAW usage with the ASIO driver.
1. Could this be an internal PSU issue in the MF II? I have a 12V 1.25A PSU I could try, but have not yet done so.
2. I'm only using Analog Outs 1+2 and the S/PDIF out. Would deactivating all other devices in the DSP settings reduce the strain on the interface's internal PSU?
3. Maybe a loose host cable port in the MF II? I thought about playing audio and removing the host cable from the MF II in order to try and reproduce the issue, could removing the cable during playback damage the interface and/or PCI card?
Thank you for reading all of this, much appreciated.
