iOS app constantly crashes when using Bluetooth


Just like the title. When using Bluetooth like a Bluetooth dac/amp, headphones the app plays for about 30 seconds before crashing. This has only occurred recently but it is suddenly occurring constantly despite me having used the same devices for months without issue.


Thanks for reporting!

What VOX + OS versions are you referring to?
What music source do you use for streaming purposes when VOX app crashes?
Does the crash still persist w\o Bluetooth streaming?

I would need to ask you to provide us with step by step description of what had been done before app crashes, so I could pass it to the QA team and get this issue reproduced in our conditions.

Thanks in advance!


Hello sorry for my super late response.

Currently using iOS 13.4.1. Vox app on iOS is up to date. I stream a variety of codecs but mostly flax, this issue occurs when streaming cloud files as well as local files, doesn’t seem to matter what codec.

If I stream files from the cloud to Bluetooth, it will play for almost exactly 60 seconds, but sometimes music will play for longer. I can never get through an entire song without it crashing. This occurs whether the screen is locked or if the app is running in the background. Currently running in iPhone 11. This issue doesn’t occur when NOT using Bluetooth.

I did a recording of my screen managing to capture the issue, but you won’t be able to hear audio. I will upload and link here shortly.


Please see this link to recordings of the app crashing


Have uninstalled and reinstalled but the issue persists.


Thanks for your post!

We would need to know more about your setup, we suppose it is iPhone + BT speaker?
What BT speaker do us use?

Please try to use Keep Screen Awake in VOX > Settings and start playback using the Bluetooth output to check if it will work OK in this conditions?


Hi thank you for getting back to me! So the issue occurs without pretty much 100% consistency when I connect bluetooth in my car, and when using bluetooth DAC’s such as my Fiio BTR5. This is on the latest version of iOS on an iPhone 11. If I do not use Bluetooth the app always runs perfectly. I will trey the Keep Screen Awake setting you mentioned and report back if I have any different results.


Update: no difference, app stalls after a moment of use and then crashes.
