Voulume gain on SPDIF out when TV source selected

[muffin]

Hi

Its possible to set higher volume gain when TV Source is selected?
When im watching HDMI source (HTPC) volume gain is great. On TV source is low.

I think.... software to set this woud be great. App to set default SPDIF volume different to any source.

SOLVED: Enter Factory menu and in sound options set SPDIF PCM Gain from -9db to 0 db. Now TV source gain is OK.
