Do dac's work on the Xbox Series X?

Thank you for posting this, I am currently in this same position.

Buying my Sundaras, which need an amp/dac combo or individually, But I dont want to buy another dac/amp when the series X releases.

I will keep an eye out on this thread.

I got my 2 channel DAC connection to xbox one x via optical out. It only works when audio setting is set to stereo uncompressed. The sampling rate shows 48k.

I am far from an audiophile but recently have taken interest in improving my audio. I invested in a pair of Beyerdynamic mmx 300 2 (based on the the dt770 model). The sound is great but I was looking for a dac/amp with mic input that I could use with party
chat that would be "future proof" with the series x and the loss of the optical output make it complicated.

I was maybe looking at the xblaster g6 but at the moment it doesn't seems to support the party chat and not sure will be compatible with the series x.

Anybody would have any advice for an amp/dac outside the the astro mixamp which I keep hearing very mix review.

Again, I wish we could get someone from Microsoft to take an interest in getting some answers for us. I'm pessimistic about the relative priority that will be given to sound devices and expect we'll be stuck with "official licensed products" using proprietary
hardware and connectivity protocols.

On PC this would be an easy problem to solve--there are myriad options from which to choose.

One possible approach would be to use a DAC/Amp with integrated microphone controls like the Schiit Hel: https://www.schiit.com/products/hel

Another approach would be to use an audio-only DAC + Amp stack or combination DAC/AMP then use a USB mic, for example, for chat. I use a Blue Yeti mic for chat and any of several DAC + Amp stacks that I own for audio. This works great if I happen to be
playing a Windows 10 game, and it works OK if I happen to be using streaming to pay an XBox game through my laptop, but it has serious limitations and doesn't work at all straight from a console.

The best answer I've had for pure XBox One gaming was to build my own headset from a Focal Elegia heapdhone with a modmic, then I plug that straight into my controller. It works, but I'm sacrificing audio quality by going through the controller, and plenty
of headphones require more amplification than the controller could hope to provide.

Do you have an Xbox One or a Series X? Those are 2 different consoles. If the disc you bought is only for the Series S/X, it will not work on an Xbox One.
