Channel muting when mirroring (QA403)

Does the generator channel mute setting also work with mirroring? maybe I am doing something wrong, but despite the mute setting both DAC channels generate the same signal…

Can anyone check this issue? I’m posting the screenshot with mute left enabled - yet both channels still active

Not sure what is going on with your muting, but have never seen commas where there should be periods in your data…

Apparently, the application uses the decimal sign, which is defined in Windows. I am from Poland. In Polish, the decimal sign is a comma, not a period.
I have to admit that there are problems with it, especially for an engineer, programmer or computer scientist. I use the period.

Hi @yegolebi, the muting doesn’t work with mirroring, but it can be investigated. It’s not clear if it should be handled at the Windows level (via system volume and/or balance) or at the WAV generation level.

Ok, I learned some Polish today… :smiley:

@matt Any follow up on this? I’m having the same issue with QA401 and need to do some product testing with isolated left and right UAC2 audio.

Hi @tkuzma

The muting was fixed in release 1.221 for the QA402/QA403 in the QA40x software. it’s a fairly large change and it won’t be fixed for the QA401 as that product reached end of life some time ago.
