Why does Amazon Prime have such bad sound quality

I watch Netflix, Amazon Prime and Disney Hot star in my gaming PC, and use HDMI cable to connect it with my 43 inch LG TV. I can directly watch these channels in the TV. But the reason i use PC because my Edifier 1280dbs when combined with Edifier T5 sub-woofer produces excellent sound quality. The onboard speakers of the TV are no match to it. But while watching online streaming channels the sound quality specially the dialogs in Amazon Prime is worse. Does the problem lies with the contents of these streaming channels or i can make it better with some change in settings?

There is a dialog boost setting available during playback. Try it. Moreover, the PC app or browser experience is much worse than TV apps/TV boxes.

I did use dialog boost, it doesn’t help. The reason i use PC is because that 2.1 Edifier speaker system that I am using (Edifier 1280db with T5) if much better than the onboard speakers of TV

other than that you can try selecting the audio track that’s stereo or Dolby, if available and your fire TV supports it.

Your speakers have optical input, you can connect them directly to your TV via toslink cable. Not sure if it’ll help with the sound quality issue you’re facing or not though. If you want I can try on my TV and tell you how it sounds compared to browser. Let me know which show I should check out where the issue might be more apparent.

Thank you. Countdown TV series. If I connect those speakers directly to TV, then I have to change the audio channel from 5.1 to 2.1. How can I do that?

Are you using any equlizer or sound modifier like Sonic Suite Spatial Sound etc. ?!

If yes then you need to make changes as per audio/video/communication or disable those.

Not necessary, 5.1 and 7.1 will usually be automatically downmixed to stereo, or just turn off Dolby Digital and/or DTS on your TV. I’ll have a listen and update you, if there’s any difference between browser on PC and TV app.

no and i don’t think that option is available

Alright so with some quick testing on Countdown. Here’s what I observed:

  1. The PC app is god awful.

  2. The audio is indeed pretty bad on PC. Audio on my PC is played through a USB DAC to my studio monitors. Even with dialogue boost it’s not great tbh.

  3. Same scene, same volume, same speakers, and the same DAC connected to the TV via HDMI Arc, it’s quite a bit better to be honest. Dialogues are much more intelligible, and overall the audio is not as muffled and teeny.

Overall I would suggest giving it a try via the toslink cable, I think edifier would’ve included one in the box. Even apart from this, HDR decoding and Dolby Vision and stuff are just handled plain better on a TV.

In my gaming PC…

AMD Ryzen 9600X, Gigabyte B850 Gaming, Asus AMD Radeon 9060 XT 16GB, Corsair CX 750, DDR 5 Crucial 32 GB, 1TB WD SN580 NVMe SSD, 27 inch Alienware AW2725DM, 8: Heat Sink: DeepCool AG 400 , Corsair 3500

I thought the sound output is much better than the sound output of any TV sound.

In my PC playing games, or streaming some UHD YouTube channels, playing offline movies the sound quality is excellent. The problem only lies with online streaming channels I will try connecting the speakers with TV once I get back home

Thank you, I will do that once I get back home

Which cable do i need to connect to TV can you show me the picture

this is the tv i have

Most probably the audio in Prime video is compressed for bandwidth. When compared with Netflix Prime Video audio is very bad.

It looks like this:

It should’ve come with your speaker.

Trust me Prime has low sound compared to Netflix and others. No wonder I have to up the volume by 8-10 nos. on my tv remote.

IF on a pc you can do various tricks esp. if sound mixer gives you a dedicated option for prime to individually adjust the vol bar.

i don’t think i have that cable. Yes the problem is with amazon prime. With Netflix and Disney Hotstart its fine

What do you call it? I am going to order one

Just search toslink or optical audio cable.

But as others are saying now, it seems prime is just inferior to other streaming services. I don’t watch much on streaming services so I can’t comment on it.

Doesn’t hurt to try out the cable though, it’s pretty cheap usually.
