Valve have pushed out SteamOS 2.67 beta with some minor but useful changes to the compositor, pulseaudio and boot-up. It also fixes as an issue with The Talos Principle.

Changelog:
> steamos-compositor - Prefer HDMI/DP over other types of displays. (patch by Coucouf)
> steamos-base-files - Plumb Alienware Deep Sleep toggle through the control script.
> steamos-modeswitch-inhibitor - Fix an issue where The Talos Principle would fail to start.
> grub - reduce screen flashing during boot
> pulseaudio - dynamic profile availability
> Usual bug fixes and security updates

I am hoping the pulseaudio changes help when you unplug USB headphones, as previously the audio wouldn't correctly switch back over which was a really annoying problem. I haven't had time to test it myself, but it's on my todo list of issues to re-check and send to Valve.

The grub changes should hopefully make SteamOS boot up look a little nicer too.

You can grab the beta by opting into it in the SteamOS settings.

hm, I encountered problems with Metro and Kodi, that can lead to sound stutter in case when:

1. kodi is started, some film watched, kodi then quit and a game launched: the game-sound stutters heavily then
2. in metro when for example lots of loud firing happens in some heavy-action scenes, then suddenly at half the magazine fired, the same stutter occurs just as after 1.

I am using HDMI 5.1 over nVidia video card.
the only solution for me was to restart the system. So basically after every movie-session a restart is required to avoid that issue.
this happens at least with the current built, I opted-out from the beta since I had some issues once and don't want to mess around this again.

does anyone have similar problems? the mentioned pulseaudio update does obviously not address this.

Quoting: GuestWith nvidia now having dkms in their proprietary driver, hopefully soon we'll have pretty-looking booting screens, too.

Sadly, we won't, because it doesn't use the kernel implementation of KMS and lacks fbdev driver. :-(

I'm really excited about the GRUB updates. Ubuntu 16.04 Beta 2 also has an updated GRUB version, so now when I'm booting, there's no annoying kernel messages.. It's so nice ;_;
