I tried editing /opt/sbin/mt-daapd-ssc.sh, and used the following:
$FLAC –apply-replaygain-which-is-not-lossless –silent –decode –stdout “$FILE” | $WAVSTREAMER -o $OFFSET $FORGELEN
Unfortunately, my de-underclocked NSLU2 does not have the horse power to drive it. It was constantly buffering. Does anyone know of anything else I could try or if there is another NAS out there that has some more horse power?
