Still having this problem in 2020 (18.04)
Spent the last 4-5 hours trying to fix it.
Just found this thread.
Not sure how relevant (new to Ubuntu/Linux since 2019), but I noticed this...
When running 'sudo lspci -v'
BEFORE SUSPEND/SLEEP
00:1f.3 Audio device: Intel Corporation 100 Series/C230 Series Chipset Family
HD Audio Controller (rev 31)
Subsystem: ASUSTeK Computer Inc. Sunrise Point-H HD Audio

Memory at dd428000 (64-bit, non-prefetchable) [size=16K]

The IRQ number is changed. Not sure why that is happening or if it
should be of concern, or creating some sort of conflict?
However, when I run 'pacmd list-cards', I see 'alsa.long_card_name =
"HDA Intel PCH at 0xdd428000 irq 141"', so I'm wondering if the OS gets
confused somehow upon sleep/hibernate?
I can't get any fixes to work besides rebooting - would really love even a
temporary fix here.
(the old fix doesn't work for me on 18.04
