1. Make sure firmware is current on all devices.
2. If that doesn't help, consider:
a. Try AVS Forum.
b. Tell Visio that if they can't fix it, back it goes. Other sets work so it's their problem and you don't want their problems.
Good evening. I just purchased a M507-G1 Vizio Quantum yesterday and I am having some issues with linking my soundbar. If anyone has any thoughts I would appreciate it.
I have an LG LAS551H and a SK6Y sound bar. The SK6Y is the newest and I had both previously hooked up via ARC to a Samsung 49MU6290. I had great sound on both and the LAS551H would sit at about level 12 and 30 out of 100 would boom. The SK6Y would usually also get to level 12 and boom at about 27.
Yesterday I purchased the Vizio Quantum and connected the SK6Y via ARC. The sound comes out a lot more muted through both bars, as I tested both, than they did on the Samsung. The LAS needs to be set about 25 and the sound doesn't change much up until 80 now. The SK6Y needs to be at 24 to be where it would normally have been at 12, and that tops out at 40. This happens when using my DVR and my Samsung Blu-Ray player.
I contacted Vizio last night and they told me to call LG as they could not help me. I called LG and they said since both bars worked on my Samsung fine, and I also have a Panasonic Viera (goodness, I'm getting old) that it worked with also that it must be something with the Vizio. I called Vizio again and they said they could not help as they didn't want to 'mess up' the settings on my bar and that was it.
Here is where it gets weird. I have a Nintendo Switch hooked up via the input on the soundbar and that is fine at about 14. I watched Youtube via Smartcast and suddenly the 14 boomed! When I went back to normal TV, though, as well as through the Blu-Ray the sound was muted.
I am confused by this. I have good sound directly through the bar (switch) an through the apps but via any input into the TV I get low volume. I tried changing from PCM to Dolby, changing to an optical cable, changing HDMI cords (as they are all high speed cables with ethernet and all worked before) and the only thing that made a difference to get where I am now was to change to PCM.
I contacted Vizio again this morning and the gentleman I spoke with did a 180 from the woman last night. He was helpful, professional and took the time to go through some steps. He determined that they would send out a repairperson to see what could be done.
The closest I came to any issue such as this was when I hooked the LG bars to the Samsung TV when trying to use Hulu (or any app) through Samsung's smart TV itself we had volume issues. Samsung's techs replaced the main board and it still happened which they could only attribute to the bar and the TV not communicating well and causing a hiccup.
Any help would be sincerely appreciated. While I admit I am no audiophile I never had trouble and always did fine connecting equipment before. The TV was exactly what I wanted (as I needed 4 HDMI ports and have had zero luck with switches over the years) and the price was good to boot. But especially considering I just purchased the SK6Y a couple of weeks ago and I'm not getting good sound I'm not sure what to do next.
