Hi RizZy,
Thanks for coming back to us on this one. The channel volumes can be down to quite a few things so it may be difficult to pin point the issue and ultimately, it's not something that Virgin Media control.
Different channels may use varying audio compression techniques and standards. Some channels might prioritize dialogue clarity, while others may focus on music and effects, leading to perceived volume differences.
Audio Formats also play a part and channels may be broadcast in different audio formats (like stereo, Dolby Digital, etc.), which can affect how sound is delivered and perceived. Some formats may be louder or softer compared to others.
Something to try can be going into the TV's audio settings and explore the options. Most TVs have different sound modes, like Cinema, Sports, or Dialogue Boost. You can also adjust the equalizer to balance the sound frequencies
You might also notice that some TV channels sound different from others because of the audio format. For example, a stereo format might sound louder than a surround or high definition format.
Let us know if checking any of this helps 😊
Thanks,
