Audirvana+ problem: random muting

[Christmas]

Hi,

I am experiencing a problem with Audirvana+ since a while now. I have been updating to all the latest versions hoping to get a solution of the problem, but no chance.

I use a Mac Mini connected to a McIntosh MCD-1100 that I use as DAC and a Qnap as music storage.

I have the same configuration since 3 years now and this problem is new.

 

While playing music Audirvana randomly mutes: the player is still reading music normally, i see the playing track bar lapsing the time, going to the next track, but no sound. If i stop, not pause but stop, it will restart playing regularly and then it will do it again.

 

I thought there was a problem with reading files from the Qnap so i connected a USB HD but I had the same issue.

 

anybody can help?

 

thanks

I believe you will find your problem is the connection between the MacMini and your MCD-1100. Check/re-seat (or swap-out) your usb cable or optical cable (whichever you use).

I found that I minimize the drops when I disconnected the internet from the Mac Mini. Larry

I have already tried.I can try to change the USB cable though and see what happens...

thanks!!!

You can go into the About this MAC in finder (black apple)

then open system report... click USB on the left panel...

check if your DAC is on ''alone'' USB 2 or 3 (if you have) port.

 

my external Hard disk is on alone too on fast usb port.

any other suggestion??

What can happen is you mute the internal speaker. Plug in the DAC, and it will be used as the system, muted. Then start A+ and coreaudiod will keep the DAC muted despite the internal audio having stopped using it and using the internal speakers - muted. Not sure where the bug is (my best guess is coreaudiod), but the following will fix it:

 

* Quit A+

* option-click on the sound in the menu bar and select the DAC for system audio

* Turn up the volume to max

* Start A+

* Mute the internal system audio (now using the internal speaker)

 

This assumes A+ is configured to have exclusive access to the DAC.

Hi,

thanks for your tip I will try tonight.

 

only one point is not clear:

Mute the internal system audio (now using the internal speaker)

 

in the I leave the internal speaker as the active speaker in the system even if muted?

of course A+ will use the DAC anyway as the preferred audio device

thanks!!!

anyway...confirmed is the USB cable

just to say a big thank you to Audio Quest for being very professional with their after sales, as you know way more difficult than sales...

to make the story short: in 5 days cable was returned, checked, did not pass the the test, new cable was sent.

 

great!!!

 

thanks AQ!!!
