Seems you're right. And it seems the issue only affect the hdmi/dp sound devices on my nvidia card particularly, no matter which or whether any drm driver is loaded or whether a monitor is connected to it. I just enabled my iGPU and I didn't experience the same huge delay with it, if I set "id=NVidia enable=0" to snd-hda-intel. I am gonna post an ouput of `pulseaudio -vvv --log-time` with my only DP monitor connected to my motherboard's DP port instead, plus the nvidia blob driver uninstalled, and these: [tom@localhost ~]$ grep . /etc/modprobe.d/* /etc/modprobe.d/nouveau.conf:blacklist nouveau /etc/modprobe.d/snd-hda-intel.conf:options snd-hda-intel id=HDMI enable=0 /etc/modprobe.d/snd-virtuoso.conf:blacklist snd-virtuoso So the only card left is: [tom@localhost ~]$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 8: HDMI 2 [HDMI 2] Subdevices: 1/1 Subdevice #0: subdevice #0</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
