I've been using an Asus Essence STX II discrete soundcard for a while, and it's been great with community drivers, but with my upgrade plans for a new PC, I'm looking to switch to a DAC instead. I currently connect my Logitech Z906 5.1 speaker system via optical, and I want to keep it running the same way without using a soundcard. The problem is I've tried switching to DACs before but they never recognize my setup for 5.1 sound. I need a clear, step-by-step guide to set up a DAC with my Z906 to achieve 5.1 output on Windows 11 24H2. Any recommendations for a good DAC would also be appreciated!

Just to clarify, when you connect your Z906 via optical, it already has a built-in DAC. If you remove the soundcard, you'll need to find a DAC that can connect to your PC via USB and provide a compatible output for the Z906. It's essential to realize that the Z906 is likely acting as the DAC in your current setup.
You're right; a soundcard is generally a DAC. Since your Z906 is set up for optical, consider just using the analog inputs on your motherboard. Most modern motherboards can function as a decent DAC outputting through three 3.5mm jacks which can be connected to the Z906. Just switch your audio settings to 5.1 in the drivers.
That sounds great! But would that mean I’d need separate cables for each speaker channel instead of using optical?
If you want to stick with optical but also use a standalone DAC, you'll need one that supports Dolby Digital Live or DTS Connect to encode the audio signals correctly. Otherwise, all you'd need is some 3.5mm to 3.5mm cables to connect the Z906 directly to your motherboard. Just be aware that some motherboard layouts can limit your PCIe lanes if you have multiple NVMe drives, which you've mentioned.
Yeah, I hear you. I'm looking at a motherboard that will limit PCIe slots as well. Is that a common thing these days?
I get what you're saying! If I replace the soundcard with a DAC connected by USB, how can I connect it to the Z906 without using optical?
