audio: When the system load is high, there is a high probability of popping sound when playing AudioTrack created with ToneGenerator.

When creating the AudioTrack with ToneGenerator, the frame count used is 0. The frame count calculated by Threads is too small, leading to a low tolerance for the AudioTrack thread runnable, which can easily result in insufficient data being written as 0 data.

Bug: 406127575
Test:
1. Incoming call in the game scene.
2. Answer the call and then hang up.
3. Observe the hang-up sound.
Flag: EXEMPT bug fix
