I am using a Samsung hw-j450 soundbar connected to a Samsung 80 inch uhd TV via the optical ports. It has a Bluetooth connection to the woofer. It was not a bank breaker an does a good job.
Try closing the tank valve. Disconnect the tank.
After 1 minute reconnect.
Then slowly I repeat SLOWLY open the tank valve. This may not be your problem but it was mine.
A lot of very good advice has already been posted. Not much I can add, that being said I am a fan of a revolver for the reasons previously stated. I personally like the Tarus Judge that supports both 410 gage shotgun rounds and/or 45 caliber rounds.
