I have a Windows 7 computer I use for gaming, and a Linux machine I use for everything else. Everything else is relatively easy to switch (one plug for keyboard/mouse, and the linux box uses VGA while the Windows 7 is using DVI so it's just an input toggle ), so a KVM seems over kill, and most are pricey and do not receive great reviews. The audio jacks are hard to reach and thus hard to switch. These computers sit close to each other, one is just buried in a desk.
What I'd like to do is have Windows 7 be able to play any sound output on the Linux machine. This would mostly be for video's on the internet (youtube) and video's played via Smplayer (tv shows).
Other suggestions are welcome it may be there is something I haven't considered.
