I just bought a Magnifi sound bar. Some speech is barely audible. How do I fix it?

if you can't find a audio output setting for pcm in your cable box, try using an optical cable directly from cable box to sound bar. I had this issue and apparently optical gave me PCM. This is probably because my cable box is old and I need a new one (ha) most people will probably not have this issue but figure I'd post my findings anyway

Note- my setup is as follows: I have my cable box connected to my sound bar via hdmi1 and then hdmi arc is connected to the tv. every time I turn on my tv, the soundbar comes on automatically and default to hdmi1. hdmi1 usually works fine but sometimes there is a certain tv show or channel that doesn't seem to have any vocals, so I hit the "TV" button for optical input and voilà! full sound and clear voices.

another thing to note is that if you connect your cable box directly to your tv rather than to one of the sound bar hdmi input, then you may have to change the audio setting in your tv itself rather than the cable box. I have found that the light on the sound bar will be an orange/red color when it is pcm versus green for bitstream or dolby, so fiddle with the options in your tv audio settings until you get a orange light on the sound bar.
