as i had pointed out in another thread, this was updated to be within spec. The initial algorithm had an issue that caused volume stepping to be loud which we had many complaints about.
the algorithm was fixed to reflect what the volume stepping should be. While before it was louder, it actually could be considered a bug that it was that loud. Now it is back to normal.
there are no intensions of changing this back at the moment, since now it is properly within spec. i only noticed the outout volume being lower when connected directly to tv, however when going through an amp, the audio is normal and is unchanged.
