Happily your AVR had front l and front r pre-outs.
Now you need to go from those outputs into a HT Bypass INPUT of your front speaker system: either a preamp/amp combo or an integrated amp with HT Bypass.
HT Bypass Input lets the AVR control the front volume along with all other channels when in Video Mode.
the front system is used for either video fl and fr OR music fl/fr.
think thru any sub-woofer, if from the AVR, it will NOT be on in music only mode.
