Who this guide is for
This guide is for users with DLNA speakers, UPnP renderers, network receivers, or AV receivers who want full Windows system audio rather than file playback from a media library.
Compatibility constraints
Many DLNA and receiver workflows are built for media files, not live system audio. Discovery, supported codecs, buffering, and input selection all matter.
ToneSpan status
ToneSpan starts with HomePod compatibility. DLNA, UPnP, and AV receiver support are useful demand signals for later compatibility work.
What to report
When joining early access, include the receiver brand, model, wired or Wi-Fi network, and whether other apps can already see the device.
FAQ
Is DLNA support available in the first ToneSpan release?
The first release focuses on HomePod compatibility. DLNA and receiver support are evaluated from compatibility requests.
Why does a receiver show up for music files but not system audio?
File playback and live system audio streaming are different workflows and may require different protocol support.
Should I expect zero latency?
No. Network receivers often buffer audio, so they are better for music and general sound than live monitoring.
