    Hello,
    on my target (RPi) I experience a lot of this errors:

    @ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred@

    when I play a PCM Wave file using QAudioOutput.
    Instead, playing directly with aplay leads to no errors.

    I checked the buffer settings and they seems ok:

    @
    access: RW_INTERLEAVED
    format: S16_LE
    subformat: STD
    channels: 2
    rate: 44100 (44100/1)
    period_size: 4096
    buffer_size: 16384
    @

    Any idea about?
