Been running Windows on my machine.
Just flashed over for a clean install of Stretch.

My speakers are ridiculously quiet - I have tried the alsamixer method; making sure the volume is up. Even at 100; barely hear a thing.

lspci | grep -i audio
00:1f.3 Audio device: Intel Corporation Device 9d71 (rev 21)

cat /proc/asound/cards
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xa1328000 irq 132
Any ideas?

The default Debian install includes pulseaudio. Make sure pavucontrol is installed, run it, and try to boost your output volume for whatever application is too quiet.

This also might be Skylake hardware, in which case it would benefit from firmware-misc-nonfree and the 4.15 kernel from stretch-backports.
The MX Linux repositories: Backports galore! If we don't have something, just ask and we'll try--we like challenges. New packages: Kodi 18.7, Strawberry 0.6.12, Pale Moon 28.10.0, Xscreensaver 5.44, Krita 4.3.0, Foliate 2.3.0

The pavucontrol allowed me to bring the volume up a bit more.
I will take a look at the 4.15 kernel and see if that solves the issue.

This may be a bit of a dumb question - but part of the reason I love Debian is because it doesn't give me as many hassles and crashes as Ubuntu. If I bring the kernel to 4.15 would that cause my system to be unstable?

Just curious.
Thanks for the help.

A newer kernel version will bring the risk of regressions and new bugs, yes.

Also, the backported kernel must be always updated (because of vulnerabilities) but is always out of date (because backports are drawn from testing rather than sid); it isn't really the best option for Debian stable and should only be used where there is a clear need (IMO).

Have you tried adding firmware-misc-nonfree? That might be enough.

(Perhaps remove the caps in the thread title, shouting is considered rude by some.)

i'm pretty sure windows adds some post-processing to its sound, "boosting" it somehow.
i remember the first time i used linux, i thought it sounded flat.
then i realised that's the clean sound.
just crank up the volume, install an equaliser and/or get speakers that have actual bass/treble knobs.
i doubt a kernel upgrade will do any good here.

The drivers on Windows are just better optimized for your hardware. I too have problems with laptops internal Realtek card, the sound is about 40% lower than on Windows. Newer kernel might help, but so would newer version of pulseaudio.
On Sid, I have better sound quality, at least. And the cracking audio is gone.
