As long as the stream is steady and there are no dropouts, you won’t notice the latency because there’s no visual element linked to it. If you’re using Bluetooth only to stream music, latency is much less of an issue. In a worst case scenario, you’re stuck with the previously mentioned latency of 150 milliseconds. You’ll find them in newer devices, but having one inside your headphone is of little benefit if your TV is outfitted with an older radio (and vice versa). And while aptX LL is great, it’s not universally supported. Both of those scenarios, however, depend on the transmitting device and the receiving device having those capabilities. And newer iterations of Bluetooth–version 5.0 and above–have a feature that automatically negotiates latency. although I heard that it then creates a new issue with input lag for games.Īlternatively, if having an eARC sound bar would likely resolve this then I can do that too, this is still under the return policy.Converting a digital audio signal to an analog waveform you can hear takes just a couple of milliseconds, but transmitting audio from one place to another takes time: 40 to 50 milliseconds using a low-latency codec such as aptX LL. in which case I should look for one that can support 4K pass though because it looks like this one can't. I'm not sure if directly connecting the PS5 to the soundbar would fix my issues. There is a sound mode setting such as game, standard, dynamic, etc. The last two settings appear to only work with an eARC connection, so I'm guessing that my sound bar being ARC and not eARC means that they are not usable.Īs far as I can see, no options other than eq settings. Here are all the relevant audio settings available to me:ĭigital Audio Output Format: PCM, Auto, Pass-Throughĭigital Output Delay: Range(0 - 250) default at 100 I should be setting my Digital Output Audio Format setting on the TV to pass-through but according to that it only works with eARC enabled, so I'm not sure what else I can try. The ARC port on my soundbar is not fast enough for my TV's eARC port, so I went into the Professional Settings for TV's sound and disabled eARC output (I was under the impression that this should be on, and it would just default to ARC but it looks like I was supposed to turn it off) I saw online that setting the sound output to DTS Virtual X (and PS5 sound to Dolby) would help because of lower latency, but that did not help either.įrom the previous post I made here, I learned the following: I tried both audio sync settings found on the TV and on the soundbar and the TV one didn't seem to have any effect and the soundbar one just made it worse, so I set it back to 0. Audio was out of sync and started playing after it was supposed to.Īt first, I thought it was the HDMI cable coming out of the ARC port and into the TVs eARC port because I just pulled out some random generic one I had lying around, so I switched to optical, but that did not help. This is not viable because it appears that the soundbar cannot support 4K 60Hz pass-through, because my PS5 was locked at 1080p and produced a very crisp, but way over saturated picture with visible artifacts and lag.Īfter connecting my PS5 back to the TV HDMI, which isn't a big deal as it's the only thing I use on the TV so the pass through isn't critical or anything, I started noticing audio lag. My original setup was having the PS5 connected to the sound bar via its stock HDMI cable, and the ARC HDMI port on the soundbar was going to the eARC connector on the TV. Soundbar: Samsung HW B650 (I didn't realize this was just released, so I'm not finding much info on it online) I posted a question similar to this last night but given the information that I have learned since then, I thought a new post would be a good idea.įor reference, here is the hardware I'm using:Įxternal Media Player: PS5 - I use this for all media consumption (games, movies, streaming, etc.)
