I recently added an LG soundbar (SH5B) and have been trying to figure out if I can disable the tv speakers to prevent the echo (I am manually tuning the tv sound to 0 but the remotes tend to increase both). The TV sound settings do not contain any speaker on/off option that I can find. The regza-link menu does contain an option but is disabled, remaining on "TV internal speakers". Is there any way to change the setting on this TV. Thanks.
