Airplay VS audio out

edited October 2022 in App Tips and Tricks

I want to Airplay the screen to a projector and have audio in/out through my external soundcard.
Could it happen?
It’s for having a collaborative loopy pro environment.

Did you try airplay screensharing while having audio out through soundcard?
If not, how about a USB hub?
I can see both ways not working out if I’m unlucky(:

    I can't test - no airplay capable devices here.

    But, if it does work, it will be because of plugging in the audio interface after starting up airplay. The last audio interface plugged in wins when there are multiple audio interfaces.

    A hub will make no difference unless maybe if it has a built-in headphone jack. If so, then see above.

  • Hmm hmm, i think it sounds reasonable enough to take the chance. I’ll bump the post again tomorrow to see if anybody wanna follow up first :smile:
    Hey, thanks again @Wim

  • Unless things have changed AirPlay has terrible latency. I think for most real-time situations like this people use video dongles rather than Airplay

  • This thread about HDMI mirroring may be relevant, or not, since Airplay is a different animal altogether.
    https://forum.audiob.us/discussion/43790/hdmi-out-while-using-an-audio-interface-is-this-possible

  • I believe Airplay is over wifi which helps explain its latency

  • @espiegel123 @wim
    It wont matter the latency, it’s just for sharing the screen for collective song building,
    -This part goes here, that part there.

    Only I need to make sure the audio will work seperatly :)
    Wim suggested to try plugging it in last.
    I’ll check the HDMI thing, as long as i does not have to plug my soundcard in the projector ^^=

  • In my experience, AirPlay (or Mirroring, which I think you mean) takes both audio and video. You could only switch to an audio interface by turning off Mirroring. I could try this in the morning.

    The Lightning HDMI adapter prevents connecting any other adapters, so it is not an option for you.

  • Thanx @uncledave !
    C’est la good info!
    All around!
    Looking forward to if you can try it.
    I’ll write the mail to apple after

  • As expected, it's basically a total fail. Here are the results:

    • Enable Mirroring to Apple TV. Audio and video are sent to TV.
    • Connect USB hub with audio interface connected. Mirroring stops (TV shows Apple TV home screen.) Audio sent to interface.
    • Enable Mirroring with interface connected. Audio and video sent to TV. AUM sees only TV output for audio.
    • Switching output to audio interface in Control Center disables Mirroring.

    So, you cannot combine Mirroring with audio output to any other device. I did not try the headphone jack, but no reason to expect it to work differently.

    @uncledave my hero!
    Kind of sardonistically funny to read about our iOS experiment not living up to expectation. Been there, they could have fixed it in 2009 no?

    What now where when,,
    I will send a mail to Apple. They are like “our next gen iPad has enough processing power to do whatever” , exept stream video with separate audio out..
    That’s not up to par is it?

  • edited October 2022

    Anybody got a workaround that is not entirely unpractical?

    It’s a fancy idea to stream loopy on projector,
    Along with using a launchpad together for songbuilding.
    I just like that idea.
    -Everybody is connected to a mixer, going into the soundcard, Into the iPad.

    The trouble is: these are mobile devices, running a mobile operating system. If you look in the system logs, you'll see that you're running "iPhone OS", not iOS or iPadOS. Multiple hardware interfaces are not what you expect from a mobile device, and we don't get them.

    I expect "Apple" will get a laugh out of your mail. Will you be contacting Tim directly, or one of the other tens of thousands of Apple employees?

  • I think you could use the Apple HDMI adapter in conjunction with an HDMI splitter and HDMI to audio converter. The latter two are not expensive. I haven't used them but have heard that some people have success with them.

    I’ve wanted to make a signatory letter with suggestions priorities from our community that someone can deliver to them like at that yearly meeting with app developers.

    Tips for a Music production iPad! (To be bought at 100 schools..)
    With
    -faster bandwidt for bluetooth hardware controllers(I think there is a ladder, not affecting audio latency, just controllers)
    -Headphone out
    -This here issue

    Are we not supposed to let them know?
    It would generate enthusiasms for them no?
    Thanks anyway @uncledave
    Here goes nothings

  • @espiegel123
    You’ve solved it.
    Time to make some Google

    @uncledave It goes a little something like this..

    “HAVING AUDIO IN USB-C/LIGHTNING DURING AIRPLAY

    Hi deer reader! Soon it is Christmas and I have high hopes for the season. If you fix thisI will tell Santa to increase his bottom line in the iPad delivering department.

    I want to make music collaboratively with iPad.
    I intended to airplay a screen from the music production software (Loopy Pro) to a projector, while still maintaining the external soundcard handeling recording and playback of the audio.
    The latency between what is happening on the screen and the quicker audio from the soundcard doesn't matter for this use, as its dedicated for deciding together what part goes where in the
    song.

    Do you think it could be added?
    I get it if you can’t get it in place for the season.
    I’ll still tell Santa you’ve been a good girl/boy/product developer anyway(:
    Have a great day”
