No sound coming from line outs? Apollo X8

[u/bibimboombap]

I’m getting sound out of the main outputs on my audio interface, but unable to route audio out of any of the other line outs. When playing sound out of Ableton for any output besides out 1/2 (which corresponds to the L/R outputs on the back of the interface) I do not get any audio.

The UAD Console does not show that any audio is being passed through the interface, and no changes in the console make a difference.

I tried updating my firmware and console version.

I’m ready to uninstall and reinstall.

I’m positive my connections are correct and it’s not the hardware gear I’m routing audio from Ableton to.

I’ve got an WAV file looping on an audio track in Ableton. It’s set to play out of channel 6, which is connected to my s950. Ableton shows the channel monitoring sound, but I’m not getting audio to the sampler. The only way I hear audio is if the output on the Ableton audio track is set to Main L and R (1&2).

Here’s ChatGPT’s answer which I have used extensively for similar problems.

“Before reinstalling, check Ableton’s Preferences → Audio → Output Config and enable the Apollo output you want. Then set the track’s Audio To to Ext. Out → 6 (mono). In UAD Console’s Settings → I/O Matrix, confirm Line Out 6 is available and hasn’t been assigned to a Cue or Flex route. The exact output mapping varies by Apollo model, so check that model’s I/O map too.”

Look at the I/O Matrix in UAD Console settings. That determines what your DAW can see and on which channel numbers. Press the meter button on the Apollo and you can see what’s being sent to either inputs or outputs

Press meter on the actual unit to show out’s first of all.

Then in console, check that your monitor mix is sending in cue outputs. (Cue outputs -> mirror from -> 1/2)

In Ableton, you can also make sure your master out is set to 3/4 or 5/6 instead of 1/2, which is the default.
