Apollo 8P/Twin duo combo - No sound on monitor outputs but headphones work.

This happened suddenly. Worked fine before I left the house this morning. When I got back, I get metering in console and the headphone outputs work fine. The Mon L/R outputs from the 8P suddenly stopped outputting any signal. I cranked it up to see if there would be hiss. Nothing. Headphone outputs on both Twin Duo and 8P work fine though. I'm going to try and reinstall the UAD software to see if that helps. I'm on a 2013 MBP with 16GB and SSD, OS 10.12.5

Have you checked your speaker? I would troubleshoot before reinstalling, this way you will find out what the issue was and know for the future. If the reinstall miraculously solves the issue, you will be none the wiser!

Speakers work fine. When I raise the volume, I usually hear hiss. I get nothing. It must not be routed properly. I'm going through everything in console and can't figure out why it happened so suddenly. The headphones work fine for the output. One thing I noticed that might be strange is that source says, "Mix", not monitor. I don't know how to change it though.

I have my monitors connected to Mon L/R on the back of the 8P. I have Lines 1/2 connected to the headphone amp. It's worked fine until now. I've rebooted, reinstalled. This is my I/O matrix setup. Some of the outputs are greyed out. Do I need to send this in for repairs?

No repair needed as this is usually a routing issue. The greyed out lines indicated that they are being used elsewhere. Apollo outs can only be used in one location and a time and they will be inaccessible in all other situations, daw routing included.

The main monitor output is now called MIX. Make sure that you have MIX selected as your monitor source and not one of the cues.

There could be a mismatch as to what unit is handling the monitoring. Unfortunately I do not have a multi Apollo setup, so I will defer to someone who does :)

I just hooked up the monitors directly to the Twin Duo, and no problem at all. It must be something with the 8P. I've sent a support ticket, so I'll post what I find. I love all of the new software out there. It's really great to be able to install the latest stuff, but I've also run into so many problems recently.

From what I gather. When a twin is present in a multi Apollo setup it defaults to the monitor unit. This can be changed in console, at some place ;) hopefully a multi unit user will chime in and glad you got sound :)

I sent a support ticket. I found another thread where some outputs were made inactive due to routing. I need to check into it again tonight. Source says "mix" and not "monitor". I'm not sure if that has anything to do with the sudden loss of sound coming out of all outputs on the 8P.

I've uninstalled and reinstalled the software. This can't be that hard. I'm getting no signal from any of the outputs on the 8P. Silver Apollo Twin Duo works fine by itself. If it was just the monitor outputs, I would think the speakers might be the issue. All outputs + headphone outs don't work.

Quick update. Twin Duo works fine. 8P's outputs have nothing. I tried both headphone jacks... and the outputs aren't passing audio. I'm begging at this point. Why put out a crappy product that is faulty? I'm on a MacBook Pro with 16GB RAM and a 1TB SSD, i7. This shouldn't be happening.

It is most likely not a failure. We have never seen this type of failure here on the forum. Not saying that it can't happen... anything can happen even with the best of products, but in these situations usually the simplest explanation is usually correct (i.e.: a setting rather than a failure)

Try completely disconnecting the twin, plugging your monitors into the 8p and testing the mix output like this.

Also, a call to customer service would be good at this point as there could be something I might be overlooking as I don't have a twin in an expanded Apollo setup.

Also, monitor is now called mix in v9.2 :) Cheers

If there's anything I've learned in the 30 years I've been dealing with audio interfaces, it is that 99% of the time if there is an issue it is with operator error.

While I don't use a multi-Apollo setup, as I recall reading, when doing so doesn't only one of the Apollos give Mix (monitor) out? Is it the first one in the list?

I've even invented new curse words to say to my Apollo when I don't get output, but every time the cause has been some setting I changed. Ooops.

In Console whichever unit is on the top will be the monitor unit. You can drag to rearrange the order. This is in the Hardware tab in settings, IIRC. The nomenclature changed in v9, I think. Mix is now the correct term, I believe.

The best thing to do is to power off the Twin and test the 8p as itself. You may want to consider a factory reset - https://help.uaudio.com/hc/en-us/articles/206132796-Apollo-8-Apollo-8p-Hardware-Reset

Twin reset is different, but probably not needed.

I've done the factory reset, and tested the 8P by itself. Still no sound coming out of any of the outputs. I've uninstalled console, deleted preferences, reinstalled console, and still no sound. I've rearranged it so the twin was the monitor and I got sound from the twin. The twin works tine on it's own. The 8P's outputs and headphones don't work. In the meantime, I'm waiting for a response from UA. Hopefully, it's a simple fix.

When you're using the 8p only, do you still have those outs showing unavailable?

Keep in mind the default Console and Console last used settings are NOT removed when you do an uninstall or reinstall.

It could definitely be Console and the only way to reset Console is to delete those settings directly with Console closed.

I'll post the locations, but I need to find my notes.

Thank you. I appreciate it. I did notice that too about the settings being the same even after reinstall. I deleted the preferences folder. I'll try a few other things before reinstalling the OS. The outputs aren't grayed out when using the 8P only though. Everything appears normal. Just no sound from any of the outputs including 8P`s headphone outs. I'll post a picture of the I/O matrix when I get home tonight.

There are two different files in different locations on Mac. Both must be deleted.

Uninstall the UAD software.

The main Console default lives in your Universal Audio folder in Documents. Kill that folder (probably the one you already killed).

The last used data, though, lives here - Mac HD /Users/User Name/Library/Preferences/Universal Audio

Kill that folder as well and then do one more hardware reset.

Then install the UAD software (with only the 8p connected, physically).

That should reset everything to factory. I'm guessing it's a setting for routing in the last used setting that's causing it. That's why both folders have to be killed, then Apollo reset, then UAD software installed.
