I do not know if this is a flash bug or a general audio bug as I haven't had the time to test fully, but when watching a video on youtube, for example, and if I open another app or open some settings applet, the sound will skip and pop, and small segment of it even loops for a bit before returning to normal. Such a problem is not present in other distro like Linux Mint.

But I should say that the sound quality of Deepin is excellent, it actually makes my hi-fi speakers sound like hi-fi. In Mint, they sound close to c***. I hope the issue is fixed. If anything is required, please ask. I can post terminal outputs if needed.
