Play+, Ableton USB audio glitches

[benbrantley]

---

Bug Description

Audio over USB-C fails after a little while.

Reproduction Steps

Play+ firmware 1.0.0 via USB-C to Ableton on MacOS 14.1.1.

Routing configured in Prefs > Audio > Input Config, just Stereo 1/2 selected.

Turn on monitoring in Audio track.

Hit play on Play+. Music goes through just fine.

Hit stop, a bit later. Instead of fully stopping, the Play+ sends the last ~100ms of whatever was playing, over and over again. At that point, the feed is fully wedged: nothing I can do will fix it other than disconnecting the USB-C and starting over.

Occurrence

Has happened four out of four tries, so far. Reliably happens as soon as I press Stop.

Found in

Play+ firmware 1.0.0 via USB-C to Ableton on MacOS 14.1.1.

official firmware 1.0.1 is out of beta as of today. I’m not sure if that will help this problem but it’s the new official firmware now. 1.0.0 had quite a few bugs apparently. it might be worthwhile updating & checking the usb audio again.

I’ve this exact same problem.
I’ve tried it with Ableton and Logic.

Resetting the audio driver helps for a bit, but then it goes again.
Just updated to 1.0.1. It didn’t fix this issue.

Thanks for trying this. (I haven’t had a chance to get back to it, update firmware, and test on 1.0.1.)

Bummer!

I wonder if there is a way to gather debug logs to help Polyend sort out what’s going on here.

I wonder if there is a way to gather debug logs to help Polyend sort out what’s going on here.

The best thing you or anyone can do (for any type of bug) is:

• provide the project file (if applicable, speeds up testing)
• write down detailed instructions, that reproduces the error.
• or record a video detailing all the steps taken to reproduce the error.

That’s all that is necessary really

Hi @benbrantley and everyone @here, thanks for reporting the issue and your comments.

First of all, please try following guidelines about general issues related to “Audio over USB”:

Play Firmware 1.4.2 and Play+ Firmware 1.0.1 (Final Release)

Today we launched 2 firmware updates: Play 1.4.2 which fixes many of the freezing issues being reported on 1.4.0 & Play+ Firmware 1.0.1, which officially finalizes the Play+ synth patch editor what was in beta. 1.0.1 contains bug fixes for the 1.0.1 Beta firmware as well so it is an essential update from 1.0.1 beta as well. Details about both below: Play Firmware 1.4.2 This release brings a few critical fixes and optimizations to improve stability and avoid frequent freezes that some of you h…

They can be found in Release Notes above, under KNOWN ISSUES: point about “Audio / MIDI over USB”

Please let us know if this fixes the problems. It’s also worth saying there are two other known issues logged in Backstage related to USB audio:

Previewing / changing synth patches can lead to corrupted USB Audio

Bug Description When using the Play+ with USB Audio, changing/previewing synth patches can lead to corrupted / distorted audio on the Play+ 's Audio Out. Reproduction Steps Use the Play+ as a Audio Input Device in your DAW (tested with Ableton and Bitwig) Route any of the synth channels to your DAW Use the Play+ as the Audio Output Device and connect your headphones to the Out of the Play+ Create a new Project on the Play+ Create a single synth track with some notes Go to synths and choose ACD…

Play Plus - Switching Play projects stops USB audio in Ableton

Bug Description I was able to replicate this issue 100% of the time, but when I change projects while streaming the Play+ main stereo outs over USB into an audio channel in Ableton Live Suite 11.3.13 - I have to completely reboot the Play+ until audio plays again over USB. It plays fine as long as I stay within a project, but the moment I load something else - it’s nothing but silence until I power cycle it. I’ve included a screen shot of the settings being used (nothing complicated: streaming m…

Besides this, general audio playback and recording over USB should work well if you follow the guidelines already mentioned. If you’re still having issues, please log a Bug with more specific case(s) when it fails.

@benbrantley

Reliably happens as soon as I press Stop.

Unfortunately, we cannot reproduce this case. It might be related to the project or settings you’re using. Please attach both here and we’ll try to investigate further.

Thanks for your support

Hi @quiniou.guillaume , thanks for your comment. Sorry for the troubles. Did you try to follow the guidelines under known issues in release notes? Which macOS are you using? Thanks

[quiniou.guillaume]

Hello,

Thanks for the response. Now after aggregate Play+ and Motu M4 it’s stable

[miropoly]

Thanks for the update @quiniou.guillaume , glad it’s solved for you.

What about others @here, did you manage to fix the issues?
