Netflix static/popping audio problems

[wireless]

When I use Netflix through Optik STBs, the sound that comes through my receiver/speakers has random popping and static noises. Netflix audio is excellent when I use my Apple TV but when I use Netflix via the TELUS App I get random popping and static noises. It is worse when base tones are present. In audio settings via the TELUS App there is only one English option. I am not given the choice to choose between English 5:1 and English (Original). Set top box is connected to 5.1 receiver via HDMI. My set top box is not 4k and is about 3 years old. Please help, the random popping and static noises is annoying and could damage my speakers.
