Mute doesn't work on Stellar DAC

Audio Components DACs
1

Can’t get Mute button on remote to work on any input - is this typical? The display shows “Mute” and volume 0 but the sound is not affected. Is this typical?

What happens when you switch off the DAC when it is in MUTE but still making sound?

3

The sound stops immediately. I thought that there might be a buffer which would give sound until it drained, but I left it on Mute for a minute or so and it still played on.

4

Even stranger (to me) is that the volume control on the remote will turn the volume up and down – still with “Mute” on the display showing. No jumps, no breaks, just a gradual increase or decrease in volume. Switching Mute on and off has no effect on the set volume, even though 0 is shown on the display.

This is one for the PS Experts @jamesh

It should work. Can you get in touch with us?

I’ve had the same problem with mine since day one, Oct 2017. I don’t use the feature so I haven’t bothered to get it fixed. I usually stop playback rather than mute as I don’t want the music to continue. I am interested in what the problem is to decide if I should pursue the fix.

Eh, for something like this, a factory reset would never hurt. There is a relay in there to stop the outputs, so that could be stuck in the “On” position, but I’ve never really heard this happen in the GDAC.

I was told by one of your technicians that it was an older (Oct 2017) unit and a chip upgrade was needed. He suggested a couple of options to take care of it, so I picked one and that should be that. If you have the same issue, I would suggest giving PS Audio a call.

Call PS Audio and they will lay out a couple of options to fix what was a bug in the early units.

Thanks; they pointed to an upgraded chip that should do the trick.

Hi Jeremy,

I don’t know whether it’s been taken care or not. I was told by the tech that he was going to send me out an updated DAC chip for me to install; he took my address and email information, but I haven’t heard any more about it.

OK, sent.

OK, received the new DAC chip and installed it - that did the trick! Mute works, everything fine. Thanks a lot for the quick resolution!
