My first DAC, Topping D50 iii, makes two pop sounds at the end of any audio, including system sounds.

I was so excited to get my first system. I bought two chip amps and a Topping D50 iii for my DAC.

At the end of any audio whatsoever... youtube video, reddit gif and vids... even the windows system sounds...

After the sound ends there are two pops about 1 second apart...

"pop"......"pop"...

Brand new, updated drivers, updated firmware.

Also turned off "auto" mode on the D50 which had no effect.

This is any audio activty at all.. when the audio ends. So even if I adjust the Windows volume and hear the bell sound... then it goes pop pop... Run a video... when it ends ... pop pop... gif vids on reddit same..

I saw a video that suggested disabling ALL other audio devices, even if not active.

I disabled my other interfaces, my monitor's audio... and it still pops...

Then I had to also disable ALL "recording" devices as well... still two pops.

Next? Uninstall all audio devices?

Other tries.... uncheck "let programs control this device"

No spatial sounds... no enhancements...

Also turned off the parametric eq on the DAC which was the whole reason I bought this one... no help.

Please help!!!
 
Hi @mavaction! Welcome to ASR.

In the Xmos driver panel, set Streaming to Always on:

Apparently, the latest Xmos driver version downloadable from their site has the Streaming option exposed by default, and also set to Always on by default, so this hack is no longer required there.

So you can either mod the Topping driver, or uninstall it and install the universal Xmos driver instead.

I tried this ... it was recommened on reddit. The problem is... after editing the file to make "page options" visible... There still is no new tab displaying.
 
Thank you staticV3 ... I will maybe try that soon. I'm a little wary of already turning to a 3rd party software solution on day one here. Gonna wait a little and see if any other solutions show up here. And I also have sent an email to Topping support which has yet to be replied to. Thank you very much though... I will prbably be trying this soon. But I don't want to void a return policy by accident.

It might also be worth just to double check there are no audio latency issues within Windows by using;
Probably not related though... but doesn't take long to install and check either.

What is your computer hardware? Laptop? Desktop? Brand and age? USB cable?
 
I have always found pops from dacs at the start or end of a track (or more typically an album) is related to rate changes (i.e. the resting state of the OS says 48/24 so when you play a 44.1/16 album you get a rate change then at the end of the album, you get a timed out rate change).

The keepalive params only help so far.

Not being nasty but the usual suspect Chinese DAC's tend to be the ones that exhibit this..in my limited experience with them they are the only ones that have this issue compared to the five or so other DAC's I have on hand.

I just got this DAC, and I have not experienced any pop/tick with anything in the desktop system I use it in. Are you on the latest FW for the DAC? Sometimes that will resolve issues like this. The only thing like that I hear in my system is the tiniest of pops from my speakers when I turn off the PA5 II amplifier.

I'm on Mac, though, and I know there's a few more things PC users have to download (i.e. drivers), so I'd make sure you have all of the current drivers/firmware/OS updates installed. If you have done that already, then I am not sure :(
