Audio problems

[LakeshaSings]

I keep restarting my computer (HP Windows 10 Home... 8GB RAM (6.93 used) 64-but Operating System, 1.80 TB storage (827 GB free) and I'm having trouble getting the Adobe Audition audio to play consistently. I'm using the TASCAM US-2x2 audio interface (software version 4.00 0099, firmware version 1.01). When I restart the Audition multitrack file, my "R" record buttons are greyed out- so I have to reconfigure the audio hardware- even though it was working perfectly before I shut down my computer. When I try to adjust the audio hardware- I get messages like "MME device internal error." When I fiddle around, I get the audio to play, but it starts recording the track instead of new vocals. Once I get it to work properly, (recording new audio in the R & L ear) the sound cuts out completely. And not just in Audition, throughout all apps on the computer (even YouTube videos and iTunes music) nothing plays. 

Is this an Audition problem or an external audio problem, or an old computer problem? Please anyone help!

I don't know whether it has one or not, but if you look in the Device Class option and set it to ASIO, does the Tascam show up in the device list? If it does, try using that driver; it will perform better, because it bypasses most of Microsof't's 'operating system'. And always make sure that the Tascam is plugged in before you start Audition, whatever driver you end up using.
