If you can read in Chinese and know how to move file into a program's IsolatedStorage, you could take a look at this linkAny third party media players or anything?
Hope im not wrong (actually I hope I am and FLAC is supported) but when I look at HTC Titan specs, FLAC isn't included.
Zune will convert WMAL to lousy WMA so it is useless. You can use mp3 or aac with the same quality. So the only option is Flac Player now.
I really wanted this Flac Player to work for me, but it doesn't. It won't even recognize the flac files I have stored on my Nokia 820.
As far as I'm concerned, there's still no player that'll play locally stored flac files on a windows phone.
