@Shanling Hello. I think my issue was resolved. I guess this issue happened because USB debugging was enabled. Now my UA1 works fine few days with no problems.

Some extra for this UA1 Issue report. When this issue happens I notice that YouTube app play videos 2x faster. Hope it helps recognize issue.

In DAC mode UP2 is charging or I need do charging from time to time?

Can I use UP2 as USB DAC with Android devices?

Sure. I am using the latest firmware for A10s, TB-X606. All my devices has official firmware, not rooted. This issue happens with YouTube, YouTube Music, Samsung music player, VLC. No matter what player I use.
