Exclusive output won't start (it falls back to Shared)
You switched Vesari Stylus to Exclusive output, and instead of taking over your audio device it dropped back to Shared - with a warning naming your device. Here's what that means and what to do.
The short answer
Your device turned down exclusive access for the format the app offered, so the app fell back to Shared so your music keeps playing. Nothing is broken, and Shared mode still sounds correct - your audio is going through the Windows mixer instead of bypassing it. The warning appears once, on purpose, so the app doesn't quietly retry and fail on every track.
You have three good options:
- Accept Shared mode. Click the offer in the warning to turn Exclusive off. Your music plays normally; the only difference is that Windows handles the mix and may resample or add its own effects. For most listening this is completely fine.
- Use a device that supports Exclusive. In Settings → Output mode, Exclusive works best with a dedicated USB DAC or audio interface. Many built-in laptop and motherboard audio chips either don't allow exclusive access or only allow it at one or two fixed sample rates.
- Match the sample rate. Exclusive is granted per device and per format. If your device only accepts, say, 44.1 kHz or 48 kHz exclusively, open its properties in Windows sound settings and set its default format to match the music you play most.
Why it happens
Exclusive mode asks Windows to hand the device to Vesari Stylus alone and feed it your file's exact sample rate, bypassing the mixer. A device can refuse this when:
- its driver doesn't support exclusive access at all (common on onboard audio),
- it only allows exclusive at certain sample rates and your track's rate isn't one of them, or
- another app already holds the device, or Windows is applying its own effects to it.
When your file's native rate is rejected, the app automatically tries 48 kHz, then 44.1 kHz, before falling back to Shared - so a refusal usually means the device won't do Exclusive at all, not just at one rate.
Does Shared mode sound worse?
Not in a way you're likely to hear. Shared routes through the Windows mixer, which can resample or apply system effects, but the audio itself is intact. Exclusive's benefit is bypassing that mixer for the most direct path to your DAC - worth having when your gear supports it, but Shared is a perfectly good everyday mode.
After you change the setting
Changing output mode doesn't rebuild the track that's already playing. Restart playback - skip to the next track, or stop and press play again - so the new mode takes effect cleanly.
If Exclusive keeps failing on a device you believe should support it - for example a DAC that does Exclusive fine in other players - that's worth reporting. Use the in-app report option and include your device name so we can look into it.
