Hi Alexandre, Thanks for getting back to me!
I followed your advice and did the following from a console on a few mp3 and
wav files:
# aucat -i *.wav
# mpg321 *.mp3
# cvlc *.wav/*.mp3
Unfortunately, to no avail. The stutter remains.
I also disabled wifi before trying this again. Again, no luck.
I double-checked my BIOS settings. Everything seems fine. I did notice "Intel
AMT" is enabled, but as I got functional audio with NetBSD on this laptop when
I tried it some time ago, I doubt this could be causing any trouble.
I also tried manipulating sound/volume using the Thinkpad buttons and these do
not appear to be interfering with anything. The stutter remains.
This is a bit surprising as the X250 seems to "just work" for most people based
on what I've seen online. So I'm assuming that it's a bug of some sort, unless
I'm really overlooking something here.
I followed the OpenBSD "Multimedia FAQ" instructions in combination with your
recommendation. The output seems to be conflicting as you'll see in the
attachment (hope that helps!).
Thanks again for your help.
