No sound streaming audio via 11R (High Sierra 10.13.6)

[Exoplanet]

I really can't work out what is going on here. I have no sound when streaming computer audio via my Eleven Rack (connected by USB) into an active speaker.


I have a Macbook Pro with High Sierra 10.13.6. I have the latest Eleven Rack driver, which Avid explicitly say is compatible with 10.13.6. I see 'Avid Eleven Rack' on my sound preferences, I can even record guitar with my 11R INTO the Mac, I just can't stream sound OUT through the 11R to the speaker.


I've tried every option in the 11R system preferences, for inputs and outputs. The only remaining thing I can think of is the Digital Clock issue of my 11r. Basically it says "unable to detect a valid external clock". I don't know if this is relevant when I'm not using s/pdif or aes ebu, but thats the only thing that seems to be a visible issue.


Any help would be really appreciated cos its driving me mad!

I get sound out of the 11R headphone jack into the active speaker. I do find though that its difficult to use the 11r amp sim with a garageband plugin with the cab sim. I think through headphones it plays both sounds rather than one through the other? It sound different than when i use a direct passive speaker in the macbook

A lot more details of what you are doing would help.

What exact speakers make/model, connected by what cable to what Eleven Rack ports?

What app/DAW are you trying to play Audio from (you are calling this “streaming” you literally mean streaming off the internet?)

Is the main output volume turned up?

I cannot follow what you mean by out the headphone jack into the active speaker... that sounds like you have the headphone jack wired to a speaker... why?

The speaker is a Presonus E5, only one speaker for now but planning to get another to make a pair soon.


Been trying to play audio from my computer (iTunes, Garageband, etc) through the 11r which is connected to the Presonus E5 via 1/4 inch jack via the Output to Amp 1 (Left). This goes into the Presonus E5 TRS slot here seen here https://d1aeri3ty3izns.cloudfront.ne...00/preview.jpg


The volume of the eleven rack is turned up, i might double check all the volumes but it works fine when I just plug the eleven rack into the speaker and thats it. It just doesnt play anything when 11r is connected by usb with my macbook, i.e. sounds from my mac, even when its the same configuration and it is connected and 'Avid Eleven Rack' is selected as output.



I tried the 11R headphone out into my Presonus E5 TRS input just to see if it works and it does, but its not what i want and i think there are some problems with recording that way.

Well that was easy, Output to Amp 1 is the wrong output to use. And it may also be too low a signal level and cause bad gain staging with your powered monitor (resulting in worse sound/more hiss etc.).

You should be using "Main Out L" the XLR jack on the rear panel. If you don't have an XLR cable you are likely better off just buying a whole new one to suit, easier than messing with adapters. Main Out L/R is fed the same internal signal as the headphone jack L/R.

And for next time, you have a "powered monitor" not a "speaker", that will make things clearer to other folks.

thanks so much for the help! Will get some XLR cables then.
