The sample rates outputted in dmesg and in /proc by ALSA are incorrect
due to a kernel bug.
48000 88200 176400 192000 384000
in your log means
44100 48000 88200 96000 176400 (+192000)
Basically there is a bitfield of
static unsigned int rates[] =
{ 5512, 8000, 11025, 16000, 22050, 32000, 44100,
48000, 64000, 88200, 96000, 176400, 192000 };
which gets interpreted as:
static unsigned int rates[] = {
8000, 11025, 16000, 22050, 32000, 44100, 48000, 88200,
96000, 176400, 192000, 384000 };
so the wrong values are printed and possible 192000 is not printed at all.
