Hello there
I am currently trying the demo of Audirvana on MacOS Sierra. I bought a Teac AI-503 with KEF R300. I am overall satisfied but I have an issue.
When I play normal tracks and it finishes, then switching to DSD or Flac 24 bits / 192k I have a very high loud pitch sound, like a robot.
Is this normal behavior?
Also, is there any settings I need to change in the MIDI audio menu?

Sadly i have this bug too… switching songs or albums from PCM to DSD only. Was not doing that in older version if i remember well… hoping it will be debugged in the new version coming this fall.
when nothing is playing you can set Midi at max of your dac… like 32-384, but in the end, it is A+ that will be running it when playing songs 
Hello
Thanks for your message!
Which DAC are you using?
I’ll try to record the sound, do you mind trying, too if possible?
I’m concerned that sound could damage my set-up.
And just to clarify the midi setting are bypassed by Audirvana, is that what you mean? So I can leave it at 44 or 32-384, that won’t change anything, if I understand correctly?
yes i mean that about midi settings
my DAC is Wyred 2 Sound DSD v2 Special Edition
i posted that already on Computer Audiophille you can see others ansewers about my post there:

Never thought of recording it… done it with my iphone and send it to me… it is a .amr extension ??
but it played on my iMac with QuickTime…
it is just frank zappa speaking for 4 seconds before it end. PCM 16/44 then, the short noise while passing to the other song in DSD64.
put it loud to hear it, but not on your sound system
Here is the dropbox link since i can’t upload .amr or .zip file here:

Ah mine is different:
I’ll post it on Computer Audiophile and other French forum to get other opinions.
I’ll try other player and see if I can reproduce the bug.
I ditched A+ sadly but use Roon now and very satisfied with it. I’ll go back to A+ once the bug is fixed and the interface more suitable to today’s standard.
