To put a live DJ and automated playback on the same YouTube stream, combine both sources into one program mix, select that mix as the encoder’s audio input, then send the encoder feed to YouTube Live. You can combine sources in a DJ mixer, audio interface, or software-routing setup; add a separate hardware mixer only if your existing signal path does not already produce a reliable combined output.
Before you start: check YouTube access and prepare the stream
YouTube’s encoder workflow requires a verified channel with no live-streaming restrictions in the preceding 90 days. First-time live-streaming enablement can take up to 24 hours, so do not leave activation until just before a scheduled broadcast. See YouTube’s live-streaming tips and its encoder setup guidance.
- In YouTube Studio, open Live Control Room and create or schedule a stream.
- Copy the stream URL and stream key shown for that stream, then enter them in your encoder as directed by its interface. The key routes and authorizes your encoder feed; keep it private, and do not show it on screen or publish it.
- Use the ingest instructions provided in Live Control Room. Prefer RTMPS if your encoder supports it; YouTube describes it as RTMP transmitted over TLS/SSL. See YouTube’s RTMPS guidance.
Combine the DJ and automation into one program mix
The encoder must receive one intended program mix containing both the live DJ audio and the automated playback. YouTube supports encoder-based streams using external audio hardware, but does not prescribe a single radio-station routing configuration. Choose the point in your signal chain where both sources can be heard together and sent to the encoder as one input.
Use the mix you already have, if it carries both sources
If the DJ and automation already feed a shared computer bus, DJ mixer output, or audio-interface output, select that combined bus or device in the encoder. Do not assume that choosing two separate capture devices will combine them: confirm that the selected input actually carries both sources.

Route separate sources together
If the DJ and automation are separate, bring their outputs into a common mix before the encoder. Depending on your equipment and software, that may be a DJ mixer, an audio interface or mixer, or audio-routing software that exposes a combined bus. Verify the connection types and levels for the DJ output, playback source, any microphone, and encoder input before adding equipment.
A USB audio mixer can be useful when separate hardware sources need hands-on level control and a single output to the computer. It is not automatically necessary when the sources are already mixed. Headphones are optional but useful for monitoring what is actually being sent; they do not combine the sources.

Set levels and verify the outgoing mix
- Listen to the combined output and confirm the DJ and automation are both present at usable, balanced levels.
- Check that no input is muted, routed to a different bus, or being captured twice.
- Confirm that the encoder’s selected audio device or software bus is the one you just monitored.
- Test with audio and movement similar to the planned program, as YouTube recommends, rather than checking only an idle scene.
Set the encoder’s audio format
For RTMP/RTMPS, YouTube lists AAC or MP3 audio and recommends stereo at 44.1 kHz and 128 Kbps. These are YouTube’s platform recommendations for the described encoder workflow, not universal quality rules for every audio use. See YouTube’s encoder settings guidance.
Select the device or software bus that carries the complete program mix, then choose a listed audio codec and the recommended sample rate and bitrate if your encoder exposes those settings. Video resolution and bitrate depend on the video you are sending; do not alter them to fix an audio-routing problem.
Rank #3
- PLUG IN AND HEAR SOUND IN SECONDS - USB Type-A connector with a 3.5mm stereo headphone output and a separate 3.5mm mono microphone input. No drivers, no software, no external power - the adapter is USB bus-powered and is recognized as a standard USB audio device.
- WORKS ON WINDOWS, MAC AND LINUX - Driverless on Windows 98SE/ME/2000/XP/Server 2003/Vista/7/8, Linux and Mac OSX, and compliant with the USB Audio Device Class 1.0 specification, so any system that supports class-compliant USB audio will see it. Select it as the sound output and input device after plugging it in.
- TWO JACKS, TWO JOBS - The green jack is stereo OUT for headphones or powered speakers; the pink jack is mono microphone IN for a 3.5mm mic. It does NOT support 4-pole headsets on a single combo plug, it does NOT power passive speakers, and it does NOT add surround sound - it is a stereo 2-channel adapter.
- FOR LAPTOPS AND DESKTOPS THAT NEED AN AUDIO PORT BACK - Adds a headphone and mic port to a laptop, desktop, or mini PC whose onboard jack has failed or was never there. Managed and work-issued computers can block new USB audio devices by policy - check with your IT department before ordering for a company machine.
- SABRENT SUPPORT AND WARRANTY - What is in the box: one USB audio sound adapter. Backed by a 1-year limited warranty, extended to 2 years when you register within 90 days on the manufacturer's website.
Test in YouTube before the broadcast
- Start the encoder using the stream URL and key for your test or scheduled stream. Use a private or unlisted test when that suits your workflow and account settings.
- Wait for the Live Control Room preview, then listen for both the live DJ and automated playback. A preview picture alone does not prove the audio mix is correct.
- Check YouTube’s stream-health messages and audio/video quality indicators. Correct a missing source, muted input, or wrong encoder device before announcing the stream.
- During the broadcast, continue monitoring the outgoing mix and stream health. Keep access to the encoder’s input and stream settings so you can respond if automation goes silent or a source drops out.
Music rights: technical access is not permission
Owning a track or paying for a service that lets you listen to music does not, by itself, establish that you have the rights needed to broadcast it publicly or leave it available in an archived YouTube video. YouTube’s livestream terms make the provider responsible for having the necessary rights for live and archived content, including relevant music rights, and for applicable local requirements.
YouTube scans live streams for third-party content. A match may replace a stream with a placeholder, and continued third-party content can cause a temporary interruption or termination. YouTube also says a stream may be interrupted even when the creator has a license if the rights owner has not added the channel to its Content ID allowlist. Before going live, confirm with the rights owner or licensing provider that your permission covers public livestreaming and archived availability, the relevant repertoire and territories, and any required allowlisting. YouTube’s copyright guidance for live streams explains the platform’s scanning and interruption process.
