Got a problem with pre-cuing

Using Djay pro for Android on my galaxy tab.
I got my DJ split cable by TRAKTOR and used a pre-cueing mode for a day. However, now I’m trying to play just a same as I did yesterday, the speaker part is not working. The volume is extremely low at the speaker part and popping noise coming out when I try to do something (like adjuisting the option and choosing tunes), while headphone part is just normally works.

Is it a SW problem or HW problem(cable…)? Give me a solution.


Thank you for getting in contact.
Did you check your Master Output volume and Pre Cueing Output volume?
