Can’t switch to 88200 HZ anymore

edited November 27 in Known issues

Ipad 8 ios 18.1.1 Scarlett 18i20 interface previously would work on 88200 which got me lower latency. I think its probably the update to 18 that I just did that caused it.

edit: says Could not set sample rate Either the hardware does not support it or another application is currently controlling it.

  • Should I try a reset or would that probably just waste my time?

  • @Johnisfaster

    Try rebooting your iPad for sure.

    Can you memory reboot your iPad sometimes apps don't shut down properly on iOS.

    Another thing is to connect the Scarlett 18i20 to a desktop and see what's going on there.

    Sometimes the settings on audio interfaces can get reset to Factory defaults.

  • Reboot and Reset didn’t work. Connected it to my laptop and was able to select 88200 from there but when I move to the ipad its still locked at 48000.

  • Do you have any other apps active in the background?

    Presumably you don't at this point.

    Do you have AUM?

  • No. I even tried my 2nd ipad. Same specs same result.

  • wow...


    It's really sounding like it's the iOS 18.1.1 update.


    Have you tried different adapters or usb hub's?

    Factory resetting the Scarlet 18i20 via desktop?

    What generation of Scarlet 18i20 do you have?

    I found this

    "You can only change the sample rate for the Scarlett 18i20 3rd Gen in Focusrite Control or Audio MIDI Setup - not your DAW. You can only change the sample rate for the Scarlett 16i16, 18i16, and 18i20 4th Gen in Focusrite Control 2 or Audio MIDI Setup - not your DAW"

    from Google, I haven't dived in any further as yet.


    When connected to the desktop check the digital clock of the 18i20 whether the digital clock is set to internal or external.

    It should be under ADAT or SPDIF etc, I don't own a Scarlet so you're going to have to be my eyes on this one.


    Any communications apps that would have a hold on the audio interface?

    When you connect the Scarlet to the iPad without anything running

    does the orange microphone thingy appear in the top rght corner?


    Other than that have you tried another Scarlet 18i20 with your iPad to see if that works?

  • First Gen. I bypassed the hub and used a different usb cable. It used to let me switch in Drambo. I’ll try again on my desktop to reset to factory or maybe update the firmware or something.

  • Orange dot doesn’t appear till I start Drambo. Clock source says internal.

  • Switching clock source to Adat or Spdif on the laptop didn’t work.

  • I personally would try Factory resetting the Scarlet 18i20's configuration first

    and if that doesn't work then next would be updating the Firmware.

    Have a browse on the Focusrite forums etc however at this point it's really looking like it's the iOS update.

    That's expected.

    I'm trying to figure out what could be holding the audio interface active.

    Do you have another audio interface you could try?

    or even try switching to headphones and then back to the Scarlet.

    Something that would result in the OS changing sample rate.

    Damn...

    That one is quite often the usual suspect when it comes to sample rate.

    Ahhh do you have something that could send ADAT or SDPF digital clock?

    Maybe try clocking the Scarlet to an external digital clock.

  • Christ now after changing settings for a while I can’t even get Drambo to use it over the internal speakers.

  • No other audio interfaces I can use. No spdif or adat devices.

    Now Im just trying to get it to work at all again.

  • I hear you.

    Is it going through an Apple lightning adapter?


    If it's going through an adapter

    First disconnect everything.

    Reboot the iPad.

    When it has rebooted, memory reset it.

    Wait.

    Connect the Apple lightning adapter.

    Wait.

    Connect the lightning cable.

    Wait until the iPad recognises that it's getting power.

    Then connect the Scarlet 18i20 via usb.

    You only have to wait for a couple of seconds each time however

    this way ensures that the iPad is in charge of power delivery and data transfer.


    Now check to see if dRambo or AUM sees it.


    If this works then disconnect it and do the same thing again

    except you will be connecting the usb hub after connecting

    the power cable and before the Scarlett 18i20.


    So first time round

    ipad reboot/once rebooted memory reset/adapter/power cable/audio interface


    2nd time round

    ipad reboot/once rebooted memory reset/power cable/usb hub/audio interface


    FInger crossed this'll get you back to dRambo or AUM seeing the Scarlet.

  • Bleh. Its too bad I can’t just go back to ios 17 but Im sure that would be more headache than its worth. Soon as the ipad charges a bit I’ll give it another go. Thanks.

    Okay Ive got it working at 48hz again. Now I just can’t use 88 or 44.

  • Actually, that isn't even possible. Once you update an Apple device, there's no going back.

    That's why I wait a minimum of four months, and check every forum post I see about any major OS update before I jump in.

  • Theres gotta be a way. Might not be easy. I find it hard to believe its impossible.

  • He's right, there doesn't seem to be a way unless Apple hasn't signed off on iOS 17 yet

    and even then it looks like there are quite few hoops to jump through with the added risk of loosing data.


    I know you've tried different power supplies and cables and the desktop however have you tried the Scarlett with another iPad?

    Hhhmmm something is hogging the audio, are any bluetooth devices connected to the iPad?

  • There should be a way, but no, there isn’t

  • I can think of a few more, but let’s focus on the positives

  • edited December 4


    I tried the Scarlett with a 2nd identical ipad and a different lightning to usb adapter and different cable and turned bluetooth off. Same result.

    I also connected it to a laptop and was able to change the sample rate but the change doesn’t stay when I bring it back to the ipad.

  • Thats really surprising. Kinda lame of Apple to control it so tightly.

  • edited December 4


    It gets worse. Let's say you do a full backup of your device before updating. You would think you could restore the backup to get back to where you were, right? Nope.

    Restoring a backup forces an upgrade to the latest OS version and every app. Furthermore, if there are apps you had installed but no longer exist in the App Store, they will be lost**.

    You heard me right. And there is no way out of that short of jail breaking, which is a cure worse than the disease.

    (** If you've backed up apps to a PC or Mac using iMazing's app backup before they disappeared from the App Store, you can restore them after the full restore, but only if you thought far ahead enough to do that.)

  • Presumably the second iPad is also using iOS 18.

    Okay, maybe try this from the Focusrite website using a MacOS desktop.

    https://support.focusrite.com/hc/en-gb/articles/207546475-Scarlett-18i20-1st-Gen-won-t-pass-audio-at-96kHz#:~:text=Applies%20to%3A%20Scarlett%2018i20%201st%20Gen&text=This%20happens%20because%20the%20channel,%3E%20Utilities%20%3E%20Audio%20MIDI%20Setup.

    Failing that send Focusrite an email and ask on the Loopy Pro forum

    if anyone else has a similar problem with their Scarlet interfaces.

  • I don’t have a Mac so Im not sure I can follow those instructions. Also it looks like its a fix for a problem I used to have; not passing audio at 96hz. Used to be I could select 96 but I’d get no sound. Now I can’t select anything but 48. I’ll see if I can figure out the windows version of the instructions you posted though. If it doesn’t fix the current issue it may come in handy later when switching sample rate is fixed but I still can’t use 96.

  • Maybe try changing the bit depth at 88.2kHz using either the Scarlet's native control panel or the settings within a DAW.

    So from 16 bit to 24bit, this will not change the amount of channels just the bit depth.

  • I couldn’t find anything in the settings for changing bit depth on the Focusrite software. Im on Windows 10.

    Heres a question; can anyone else whos using iOS 18 change their sample rate? I wanna know if its an iOS problem or a Focusrite problem. Or both. I’d considered getting a different interface in the past this might push me into that.

  • Windows 10 has a sound panel try using that instead and maybe try the ASIO driver as well.

    You can access the ASIO driver from the DAW you use.


    I would suggesting asking over on the Loopy Pro Forum as well and I'll keep an eye out for any users

    who may report any issues with the Focusrite 1st gen audio interfaces or indeed any of the Focusrite interfaces.
