DJM-T1 Sierra Driver 1.2 Phono/CD/Phono Toggle Bug Fix

I use Traktor Scratch Pro (2.11.0 23). I just upgraded from Yosemite to Sierra, and after installing the DJM-T1 Sierra driver (1.2.0) there is a new problem. Traktor Scratch decks are no longer detected automatically. I have to launch the DJM-T1 Setting utility -> Mixer Output, change from phono to CD then back to phono again on both decks, then the decks are detected and everything works as expected in Traktor. Important note: if I exit Traktor and relaunch it, Scratch decks are detected and work fine. But after I shut down or restart the computer, I will have to repeat the process for the Scratch decks to start working again. I did not have this issue under Yosemite with the 1.1 driver. I am using firmware v3.00. Please fix this bug, thanks. - UPDATE - SMC and NVRAM reset has made the problem intermittent.

Hey guys, sorry to hear about this! I'll take a look into this and see if our product team has any questions for you guys about the configuration beyond what you've already posted.

Can both of you let me know if you power-cycled the DJM-T1 as well as the computer? The engineers found that this issue doesn't seem to occur if the mixer is left powered-up.

True, it only happens when i turn the mixer off as well.

Does it happen if you keep the mixer powered-on?

Sorry guys, my notifications got caught up in a spam filter. Same here - I tried restarting in different order, power cycling the MacBook, restarting Traktor only, mixer only etc. Conclusion - if the mixer has been off, I have to launch the utility for Scratch to be detected. If it stays on, I did not see the issue. Thanks.

As you can see, this is a reasonably isolated incident, and while the engineers are working to determine the root cause and develop a solution, it's a low-priority issue and may take some time to resolve. Your patience is appreciated!

Have same hear, but also another problem appear.

After about 4 hours of playing well, Traktor warn me that left channel is missing and sometimes it stops tracking at all and its not working till next day.

It happens to me twice,

Any ideas?

Hi Pulse,

Any chance of a workaround or hotfix if there isn't a new driver coming?

Thanks.
