SACD iso and DSD noise when stopping or closing music player

The new ASIO driver for all Gustard DACs is now available. They are working on the website, and they are now posting firmware updates there.

The only fix I have for J River is to select DOP in the prefs. It will send the DSD file in a PCM package (it does not convert it). The DAC will then unpack it and play the DSD file. There is a new ASIO driver on the Gustard site, but the link button does not work. I've emailed them and it will likely be fixed soon. Version 5.50

I am having the same problem using J River from my laptop using windows 10 to the Gustard x26 PRO. If there is a driver fix available please let me know! This is very frustrating, I am currently having to mute my preamp during stop of playback.

Fwiw, I have the same problem when I switch from any other input on my DAC to the HDMI inputs

I did find on another forum that this is an issue with other owners of this dac and similar dacs.  A firmware update and/or ASIO driver update may help.

I tried my laptop direct instead of my home computer: same issue. I tried all the suggestions above and thank everyone for them. This appears to be something I can only get around use DSD/DOP. I'll get over it and move on.

@tempest714 ,

I am a big fan of Foobar and upscaling everything PCM to DSD, including Internet Radio and Spotify. Check the following link to make sure you have configured F2K properly.

There's a whole section in the manual about setting up Foobar.

I definitely have the latest drivers from Gustard (5.30).

Just in case make sure you download the drivers from the DAC website, don't use generic Windows drivers.

Just go DoP and fuhgedaboudit.

The manic side of me want to figure these things out, but I should probably just move on with this one unless someone else has an suggestion.

DSD Native makes similar noise intertrack via direct play on a Topping M50. Maybe it’s a a Shenzehn thing as it does not occur in my US DAC. DoP does indeed bypass it. I can't really hear a difference after cursory comparison.

I have no idea about your path because you are talking a language I don’t understand. It looks like you are feeding your amp directly from your DAC. The amp goes on last and off first. And whatever is feeding your amp should be set at zero volume on turn off and turn on.
