Neither did I with luck of sound in Beta 1.4. Switched back to Beta 1.3.
FYI If you would like to add a little native ICS UI for your Beta 1.3 music app, try music player for ICS by CyanogenMod team extracted from CM9 ROM.
Installation:
delete music.apk and musicfx.apk located in /system/app by using file manager like root explorer;
download the CM9 music app from
http://goo.gl/CckWp;
install it like any standard apks from your sd card;
done.
It's been confirmed by me the music app itself works fine and has equalizer options and DSP configration enabled, which however, is yet to be tested since they were designed for Samsung Galaxy Nexus. So if you want to modify the updater-script files to make them flashable for Hero running ICS ROMs.
Here are DSP manager install and uninstall zips (NEED MODIFYING) I found from
