I have to admit that it still does not play my music completely smoothly.
It has little pauses. I checked, and there is nothing using a huge amount of CPU when that happens, and I have plenty of free RAM. The network speed or streaming also does not appear to be an issue. I have mostly been listening to FLAC songs over WiFi (untranscoded).
On a Samsung Galaxy S i9000, 16GB international version, running Android 2.2. I know the SGS has some weird filesystem issues, but I have changed that on my phone (from RFS to Ext4), so that should not be the issue...
Any suggestions? Or any more information needed about this?
