I cant talk to anyone in my xbox live party, however i can hear them just fine.

Could be a NAT type issue or a comm ban.

Try checking these.

I hardly ever hear anyone talking in games. However, when I'm in party chat I can talk with my friends just fine. I was wondering if there was something wrong as well.

For Astro A40 users:

Configuring the Xbox One Stereo Headset Adapter

By default, the Xbox One Stereo Headset Adapter will output both game audio and voice audio which will render the mixer on the MixAmp unusable. Follow the below steps to set the Xbox One Stereo Headset Adapter to only output voice audio which will correct
this.

1) Set the mixer on the MixAmp to full voice audio.

2) On the Xbox One Stereo Headset Adapter, hold down the chat audio button until you can no longer hear game audio and can only hear voice audio.

3) On the Xbox One Stereo Headset Adapter, hold down the plus button until the voice audio no longer increases.

That’s all that’s to it! You will now be able to use the microphone from your A40 or A30 Headset on your Xbox One and the mixer will work as intended allowing you to mix between game audio and voice audio with ease. Should you have any further questions
regarding the A40 or A30 Audio System and Xbox One, please feel free to post them on this thread and we’ll respond as quickly as possible with an answer for you.

Other Notes:

[Update:] After spending the day with the headset adapter I can confirm that the above configurations do work. You will have no issue with your Astro headsets working with the chat adapter. I tested the Xbox One headset adapter with 2011 versions of Astro
A40 headsets. Game audio and voice audio sound great, I can’t wait for my new headsets to come in hopefully in time for Titanfall!

In their forum post they mention to set your optical out to Stereo Uncompressed. I believe this step is now unnecessary because the Xbox One does indeed support Dolby Digital Surround Sound through the optical out. This forum was posted before the Preview
Program went live. I’ll keep this post updated if anything changes or becomes confirmed.
