Hi,
I just finished checking using my ASUS Routers, TPLink (using DDWRT), QNAP NAS inbuild server, MM5 and from my investigation found out that router do not parse albums correctly at all. Album Artist is parsed as Artist and in case of my compilations where Album Artist is Various I do not get artists at all
For all Tracks in Albums Track # is missing and MMA sort Alphabetically tracks track with NULL Track #. I do not see issue there
Same folder served from MM5 sort same in MMA and all other apps and as Soon Track Number is filled all is resorted and on Router it stays same
UPNP Servers on routers are not complete so you get results such these. Only QNAP NAS (Mostly) and MM5 correctly list and supply Metadata to MMA and other Android clients I tested like Slick DLNA.
Devices Tested are:
ASUS Router RT-AX92U
ASUS Router RT-AC88U (Unlocked Merlin Firmware)
TP-Link TL-WR2543ND (DD-WRT)
QNAP NAS (Twonky, QNAP Media Server, MINIDLNA)
MM5 5.0.1.2433
