AudioAttributes docs: warn about small buffer size with FLAG_LOW_LATENCY

    public final static int FLAG_BYPASS_MUTE = 0x1 << 7;

    /**

     * Flag requesting a low latency path.

     * Flag requesting a low latency path when creating an AudioTrack.

     * When using this flag, the sample rate must match the native sample rate

     * of the device. Effects processing is also unavailable.

     *

     * Note that if this flag is used without specifying a bufferSizeInBytes then the

     * AudioTrack's actual buffer size may be too small. It is recommended that a fairly

     * large buffer should be specified when the AudioTrack is created.

     * Then the actual size can be reduced by calling

     * {@link AudioTrack#setBufferSizeInFrames(int)}. The buffer size can be optimized

     * by lowering it after each write() call until the audio glitches, which is detected by calling

     * {@link AudioTrack#getUnderrunCount()}. Then the buffer size can be increased

     * until there are no glitches.

     * This tuning step should be done while playing silence.

     * This technique provides a compromise between latency and glitch rate.
