Motu M series with Android, anyone

[asphaltradler]

Has someone managed to use the M4 or M2 with an android phone?
Motu doesn't support Android but some interfaces work with android nevertheless.
With a M6, it is recognized by Android and I could use its inputs with Universal USB Recorder app but didn't get any sound out its headphone output then. Also, there was intermittent noise on the interfaces output even when I used only the internal monitor function (direct listening to the Microphones).

This makes recording possible but difficult because I have to remove the interface and use the mobile phones' HP output if I want to check my recording.

Thought that could be different with an M4 or M2 with less IO ports.

Someone must have tried this?

With a Behringer UMC 202HD it is plug&play, recording and playback.

If you're looking for an interface specifically for that purpose, consider the Topping E1x2 OTG or E2x2 OTG.

Their OTG interfaces are designed to be used with Android.

Well that doesn't answer my question. As far as I know OTG isn't even necessary for that, only adherence to some common standards. I know that the non-OTG version of the topping work with Android, too, as does the before mentioned Behringer or interfaces by RME and other manufacturers.
I decided for the Motu for different reasons. The main usage will be with PC/laptop but it would be nice to use it mobile without computer, too.
The Topping seems not to be fully mature to me. Scratchy potentiometers with non-logarithmic gain in a new product would drive me mad when recording. The Motus work fine in every other aspect, so I wondered if anyone was able to fix the Android problem.

well..

I have read user comments to this and no one seems to be able to replicate the behaviour. Bad/insufficient usb power perhaps?

M4 user here..cant recommend using for android, it does not work properly (using via powered usb hub). In the end, im just using other audio interface that works without hitch

Android linux kernel uses standard linux usb-audio driver, but not all commits are picked from linux mainline. Some commits are backported, some not. Plus the kernel version on android devices is typically very old while Motu support is relatively recent, including new fixes, e.g. https://kernel.googlesource.com/pub...nd/+/d915a6850e27efb383cd4400caadfe47792623df , https://kernel.googlesource.com/pub...nd/+/73ac9f5e5b43a5dbadb61f27dae7a971f7ec0d22, https://kernel.googlesource.com/pub...nd/+/48d6b91798a6694fdd6edb62799754b9d3fe0792, https://kernel.googlesource.com/pub...nd/+/c249177944b650816069f6c49b769baaa94339dc etc.

Motu M devices are not fully UAC2 compliant and require driver quirks.
