The same bug affect my system xubuntu 20.04 over a DELL Precision 7510.
Manufacturer: Dell Inc.
Product Name: Precision 7510

Firmware Version: 1.16.3
Board Vendor: Dell Inc.
Board Name: 02H5GH
Kernel release: 5.4.0-29-generic
Operating System: GNU/Linux
Architecture: x86_64
Processor: x86_64
SMP Enabled: Yes
snd_hda_intel
snd_hda_intel
Pulseaudio:
Installed - Yes (/usr/bin/pulseaudio)
Running - Yes
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xdfe48000 irq 141
1 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xdf080000 irq 17
With nominal installation fully updated when plugged-in any headphone no
sound at all.
After the update of pulseaudio package as provided by
https://launchpad.net/~kaihengfeng/+archive/ubuntu/fix-lp1869819
inserting a cheap no name headphone I'm able to hear the sound even if a rustle
in background is present.
Inserting a SADES game headset no sound only distorted noise is audible.
To be noted that the pulsaudio mixer seems to work perfectly, having the
headphone jack inserted
I'm able to move the output sound to laptop speakers and move back but without
fixing the problem.
Last but not least the same configuration with xubuntu 16.04 worked
perfectly.

all.
