Hi-fi mode + GX off (even disabled startup exes related to it) didn't solve it. It was my main setting during years, until the noise became recurrent in W10 without a change to it.

Interesting, in the past @wimderammelaere had the opposite conclusion on his system (post). He had to force Windows to use it all the time via /set useplatformclock true (so it's 14.3KHz all the time), but at the time when I was using the DX under the same setting it didn't eliminate the...

From the uni xonar support comments, could be worth checking:

Never had the problem ever since replacing the DX with a bulk Z under W10.

Also had the problem on a AM3 based platform with 790FX/SB750.

Thanks for confirming that the latest W10 driver doesn't solve it.

@wimderammelaere Please let me understand what your fix was: a) disabling HPET on bios b) enabling HPET on bios, but forcing HPET timer all the time (/set useplatformclock true)   If it's b), it didn't work on my SB750/Xonar DX system when W10 came out, because that was my daily setting.  ...

Sorry I can't test in the affected system anymore with the DX since replacing it, but on it I've tried temporarily to disable Link State Power Management without success and the banshee scream happened, also ASPM was disabled for that slot on BIOS. On that system HPET was enabled all the time...

While using it and having the banshee scream of death under W10, I've always had my DX at default 76 CP volume and windows mixer (speakers) from 30 to 80% w/ windows sounds disabled. Btw, did anyone test the w10-only unixonar .1825 to see if it they help?

A new uni xonar package has been released with a new c-media .1825 driver that is exclusive for W10 (UNi Xonar W10 1825 v1.81a rev.2). You might try if for some miracle this has been solved.

Unfortunately it's the same base driver (8.1.8.1823) as in the latest Asus or UniXonar offer :|

geoxile is surely referring to the volume sliders on the asus control panel under "mixer" that are usually set to 76%, not the rotating volume button that also controls windows volume. In the mixer>playback, Left/Right volume will affect max windows volume and probably lessen sound quality if...

Windows Volume seems to work up to what Xonar level permits (but probably even Xonar level goes bananas when the glitch happens). IIRC, it shouldn't be set too high (default is 76 in DX?) for the best THD.

Disabling fast boot both on W8.1 and W10 doesn't help with the issue, it was never enabled on my system that was running the DX.

OT: Now that you mention it, there's also that SBA4_SII_PCDRV_L02_3_01_0046.exe for the Audigy 4 II/Pro with updated drivers I forgot, which I presume you're using. How can you access it via the main site instead of a direct google? If I go to this link, the Audigy 4's only have W7 drivers (like...

  Well, I've never had a banshee scream in these 8 months after replacing the DX (that was causing it very often) with a Sounblaster Z OEM in the same system last December.   On another computer where I'm reticent to place that DX, I'm currently using an old Audigy 2 (pretty similar to that 4...

If that helps, I've seen the issue most often with MPC-HC (Dsound output), either starting or seeking a video. But then again, it could be twice a day or once a week.

Sorry for misguiding you then. I assumed it'd pop an error if already unregistered, haven't used regsvr much lately.

That's curious. I've only seen reports in this and uniXonar's thread with STX/II, D1/DX*, all sharing the same Oxygen HD CMI8788 with AV100 label. I wouldn't be surprised if it also affects D2/D2X (AV200, also on the HDAV1.3 ), but strangely I didn't notice any report on that card (other than...

  If you redo the tweak, I guess regsvr32 should pop an error if those dlls still remain unregistered from the previous fix, other than unregistering them again.

The same as in most posts before, it seems to happen randomly when a sound is initialized. This can be right after starting or seeking a clip in mpc-hc (dsound), a song in winamp (dsound), or a clip in youtube via chrome. Also happened once inside a game menu after clicking a button that causes...

Unfortunately I've tried the fix above to disable asio drivers, so as prevent GX components from loading with windows but it didn't fix the problem (so as disabling pci-e link energy management). On my offending system, other than the usual loss of the right channel that was fixable with a...
