I bought this soundbar to replace some ageing PC speakers. It's decent enough for the price, but comes with a highly annoying 'feature': the soundbar will put itself into sleep mode after a couple of minutes of inactivity, and only snaps out of it if you turn up the volume.
Let's say you finished watching a video, you browse some website in silence for 10-15 minutes and then you want to watch another video. Now the video is silent, because the soundbar is in sleep mode, and you'll have to increase the volume to wake it up again.
What takes this from "mildly infuriating" to "highly irritating" is the fact that this sleep mode is not only activated during absolute silence, but also when the sound is below a certain threshold. Want to play some music softly while you work? Nope, the soundbar will go into sleep mode. Feel like watching a video at low volume so as not to wake up the rest of the house? Sleep mode. Some games with gentle ambient sounds and subtle audio cues will just turn silent unless you play them at high volume.
And remember, to get it out of sleep mode, you'll have to turn up the volume quite a bit to push past that threshold and wake it up again, so if you were hoping to keep the noise down, you're out of luck.
The soundbar is plug and play, so there's no software that allows you to adjust these settings. Turning off this sleep mode is not an option. It also doesn't show when it slips into sleep mode, no LED or on-screen prompts - it'll just turn quiet.
If you generally play/watch/listen at medium volume or higher, then this might not be a problem for you. If, however, you want some discreet control over the volume you produce when using your PC, I suggest you look elsewhere.
