When doing loopback between two audio card with
same sampling frequency, I noticed slow increase
of pitch_diff.
When I changed order of get_queued_playback_samples()
vs get_queued_capture_samples(), I noticed same drift
of pitch_diff but if was decreasing this time.
This seems to be caused by non-atomic consecutive
snd_pcm_delay() invocation for playback then for
capture. snd_pcm_delay() measures delay between
read/write call and actual ADC/DAC operation.
So while we get this value for playback path in
get_queued_playback_samples(), next call to
get_queued_capture_samples() will happen a little
bit later so snd_pcm_delay() may return incorrect
value.
Be interleaving get_queued_{playback,capture}_samples()
order, we divide this small error between playback
and capture paths. I do not see any issues anymore
with one-way drift of pitch_diff.

The spinner did not actually provide information about the status

Sorting the list of loaded modules makes it much easier to compare
two alsa-info.txt files, even if they are both from the same system
(since the order actually changes after each reboot).
lsmod just formats the contents of /proc/modules. After this script
calls lsmod, it strips everything but module names from the output.
This same result can be obtained just as easily by reading directly
from /proc/modules; then there is no need to remove the header line
printed by lsmod before sorting the output.
