Getting this right is actually kind of tricky.Д®ven if the clocks don't match perfectly, you'd think this would be beyond the acuity of human perception for the majority of the time. one will probably be closer to the CPU, and so will be affected more by changes in temperature due to system load. Making matters even worse, the clock speed discrepancy will likely drift over time, since the two crystals won't be in the exact same thermal environment (and it is unreasonable to expect the clock oscillators in commodity consumer hardware to have high-quality temperature compensation). So unless we do some sort of adaptive resampling, one of the devices will periodically need to drop or repeat samples (which will introduce audible artifacts) if we want to keep the two devices in sync with each other.

The clock signals used by the two audio devices are unlikely to match perfectly, due to differences in individual quartz crystals. Yeah, given a slider I think you'd be able to match the delays closely enough by ear to deal with differences in latency.Д«ut I don't think absolute latency is the most problematic issue clock frequency skew is probably trickier to deal with 'under the hood'.

I was wondering about this, but even if two playback devices did have noticeable variance in latency, would it not be a simple matter of implementing a software delay slider for each additional device after the primary, say in millisecond increments (similar to what AVR receivers have, for example) to get things close enough? Or would the delays be variable over time, for example due to changes in CPU thread priority or hiccups in one device that may not occur on all?

So, had Win 8 added this obvious feature? So why would anyone want to playback the same output signal with more than one device? Some examples:ДЎ) You want to play music in multiple rooms (zones) in a house, the amplifiers in one or more zones having a digital input (DAC)Дў) You have a surround sound system and you, say, want to use a separate device to play the surround speakers than that that plays the fronts, at least one of them being a digital input (in this scenario, the delays encountered with Virtual Audio Cable are a deal breaker)ДЈ) You are playing an instrument along with music and want to output sound to both headphones and a stereo powered by separate amps

With onboard sound and sound devices coming ubiquitously with every motherboard and video card these days, USB speakers/headsets, not to mention actual sound cards and external DACs, the number of available playback devices available to the average PC user is increasing. Plus, there are apparently delay issues and difficulties with more than 2-channel sound with Virtual Audio Cable. Yes you can make batch files, etc, to automate doing this on startup, but it's a bit messy to accomplish something that should be so simple.

The problem with this is that it requires manual setup every time you want to use it.

I realize you can use 3rd party apps such as Virtual Audio Cable that let you assign a virtual playback device that then splits the signal to multiple devices.

On the off chance that MS may have finally implemented this simple feature, it might give me a reason to upgrade to Win 8. So what's the deal with MS deciding not to allow you to use more than one sound playback device (in Win 7 anyway)?
