<pre>In the current stable (4.10.3-1) and mainline (4.11.0-rc2) kernels of Arch
Linux I noticed resampling issues when playing 44.1kHz audio using the HDMI
output of my i915 chipset on a Asus Z170-A motherboard. This issue wasn't
present in previous releases but I didn't take the time to bisect and find the
relevant commit yet.
In the following, hw:0,3 refers to the HDMI output of the HDA Intel PCH.
speaker-test -D hw:0,3 -c 2 -r 48000 -f 440 -t sine
This produduces a fine 440Hz sine wave.
speaker-test -D hw:0,3 -c 2 -r 44100 -f 440 -t sine
This produces a way lower frequency sound with clicking noises about twice a
second.
Running the same on the analog output doesn't result in any resampling issues.</pre>
