Topic: Query: Fader Positions go to zero on sample rate change

I just noticed that when the source sample rate changes to either 44100Hz or 48000Hz, the Software Playback faders all go to zero in TotalMix - but I still hear audio okay.

As soon as I slightly move a fader, they all jump up to where they should be in my snapshot. Similiarly if I change to another snapshot and go back to the first one, they go where they should be.

Very weird. Only happens going to 44.1 or 48kHz, from 88.2, 96 or 192kHz. Doesn't happen the other way around.

Is this normal?  It's a bit confusing because if you look at the faders, they don't represent what you can hear, i.e. it looks like no sound should be heard because the faders are all on zero.

I'm using a Digiface USB and I have driver 0.9843 installed. TotalMix is at version 1.95

You mean the other way around ? The faders are all down ?
If the faders are at zero, that means the faders are up, full power music.

Yes, sorry, meant zero output = -infinity on the fader.

Re: Query: Fader Positions go to zero on sample rate change

I did a test with my Digiface USB.
Changing the sample rate back and forth, 44,1 to 192 kHz,
the faders in Totalmix don't move, they keep in place as expected.
No issue at all. Sorry can't reproduce your issue.

Re: Query: Fader Positions go to zero on sample rate change

What hardware output channel is selected as current submix when this happens? Provided you are in Submix View. Is this also happening when other submixes are selected? USB errors shown then in Settings dialog?

Re: Query: Fader Positions go to zero on sample rate change

Thanks for responding. Hopefully the below makes sense:

I use the analogue line out (PH=Main), so that's the selected submix. After the switch to 88.2kHz and up, the software playback faders stay at their snapshot positions. Then when I switch to a 44.1kHz or 48kHz source, the available channels expands out, but the software playback faders are all at -infinity.  Audio is still output as normal, volume level doesn't change at all.

At that point if I click on any of the hardware outputs, the software playback faders stay at -infinity. I could click on any of the hardware outputs and the faders don't move - except if I click back on 'Main' - then the faders immediately jump back to where they should be as per the snapshot.

The MADIFace Series Settings applet reports no (0) USB errors.

They also jump back to position correctly if I select a different snapshot, and they stay where they should be if I then switch back again to the original snapshot. If I move a software playback fader a tiny bit, all the software playback faders jump back to where they should be.

It seems like there's some sort of refresh/update of the fader positions that doesn't occur immediately after the sample rate change, but does get triggered as it should with other things (like loading a different snapshot or moving a fader).

Here's a link to a video capture. There's no sound (Windows didn't record ASIO) but it shows the problem. Thanks again.
