Voice starvation with only 3 physical voices on particular mobile phones

Question

Hello!

I ran into an annoying issue that seems to only appear on a specific phone model Samsung A10.

I know that voice starvation occurs when there are too many voices and the audio thread cannot render the next frame but in this case, there are only three voices uncompressed, no plugins, fresh project, and last version of wwise, Unity 2020.3.2f LTS. A lot of other phones and PC build works fine but with this particular mobile phone the log is full of error https://imgur.com/jaj5gXj

I wonder where to look for a solution :(

Answer 1

I find a solution but the problem is still actual and I would be glad if developers pay attention to it! I opened Unity Project Preferences - Wwise Initialization Settings and changed the default Sample Rate from 48000 down to 44100 and it works! 90% of voice starvation errors were gone and the rest were not audible! After I set up Max Sample Rate to 44100 in conversion settings of wwise and rebuilt all banks, all errors were completely gone! This is a very odd problem! I tested 48khz files uncompressed directly in Unity and with FMOD and Samsung A10 can handle it and sounds perfect but with wwise 2019 or 2021 even three uncompressed files playing at the same time gives tons of voice starvation! The problem was observed on two different phones of the same model Samsung Galaxy A10, all software up to date!

Thank you!
