But how can it be at the first place?  (352 353) is already empty as
the frames.  The time could be kept in this representation, but the
frames must be integer.

Which order of calls did it result in so?

We know that some order of calls make the selection impossible like
the above, especially when both time and bytes/frames are mixed.



I have used the following ALSA configuration:

pcm.test_rate {
    type rate
        slave.pcm hw:gmdcard
        slave.rate 48000
}

and used the following implementation:

INTERVAL_INLINE int snd_interval_single(const snd_interval_t *i)
{
    assert(!snd_interval_empty(i));
    return (i->min == i->max ||
        (i->min + 1 == i->max && (i->openmin || i->openmax)));
}

INTERVAL_INLINE int snd_interval_value(const snd_interval_t *i)
{
    assert(snd_interval_single(i));
    if (i->openmin)
        return (i->min + 1);
    return i->min;
}

In addition I have enabled RULES_DEBUG.
With the following aplay command I got a period of 353 frames and a buffer of 705 frames:
$ aplay -Dtest_rate -c2 -r22050 -fS16_LE /dev/urandom --period-time=16000 --buffer-time=32000 -v Playing raw data '/dev/urandom' : Signed 16 bit Little Endian, Rate 22050 Hz, Stereo
