Reading here, audio has been an issue for years. Music shows especially are terrible. Hire a competent engineer and FIX the sound. IF service providers are bad, REPLACE them. PBS shows are 50% of the SOUND of all other shows at any time . Got it??
Sadly, WOW is carrier but likely audio may be bad for all. WITV, ETV, bad audio.
Music shows, bad sound, low and not good.
