it look like qaudiorecorder bug
in qaudioinput_alsa_p.cpp
buffer_time = 100000;
period_time = 20000;
but chunks = 8
if ( !fatal ) {
err = snd_pcm_hw_params_set_buffer_time_near(handle, hwparams,
&buffer_time, &dir);
if ( err < 0 ) {
fatal = true;
errMessage = QString::fromLatin1("QAudioInput:
snd_pcm_hw_params_set_buffer_time_near: err = %1").arg(err);
}
}
if ( !fatal ) {
err = snd_pcm_hw_params_set_period_time_near(handle, hwparams,
&period_time, &dir);
if ( err < 0 ) {
fatal = true;
errMessage = QString::fromLatin1("QAudioInput:
snd_pcm_hw_params_set_period_time_near: err = %1").arg(err);
}
}
if ( !fatal ) {
err = snd_pcm_hw_params_set_periods_near(handle, hwparams,
&chunks, &dir);
if ( err < 0 ) {
fatal = true;
errMessage = QString::fromLatin1("QAudioInput:
snd_pcm_hw_params_set_periods_near: err = %1").arg(err);
}
}
if ( !fatal ) {
err = snd_pcm_hw_params(handle, hwparams);
if ( err < 0 ) {
fatal = true;
errMessage = QString::fromLatin1("QAudioInput:
snd_pcm_hw_params: err = %1").arg(err);

Title:
QAudioRecorder recording hangs
Status in pulseaudio package in Ubuntu:
New
Bug description:
Recording audio with QAudioRecorder intermittently fails for me.
Another user even reported that it only works 1 out of 5-10 times.
QAudioRecorder seems to hang on requesting the audio to be recorded
(status QMediaRecortder::StartingStatus). When it actually works, it
properly goes from starting to recording and then it's possible to
record audio and playback.
QAudioRecorder has an error() method, but it returns
QMediaRecorder::NoError
Since it was confirmed by two people (victorp, karni) we suspect it's
a bug in the middleware rather than the apps.
A test click has been sent to Ricardo's e-mail by Victor.
