PS You don't mention whether you are using the sound on the mobo or a PCI(e) sound card, nor which video card to be able to use VLC, nor which monitor you have. Providing such info is most useful to have one's problem resolved (often) quicker.
The sound goes through the graphical card: # hwinfo --gfxcard 14: PCI 500.0: 0300 VGA compatible controller (VGA) [Created at pci.378] Unique ID: Ddhb.zvQlrOmSRQ8 Parent ID: _Znp.ZJmKoWxd6BF SysFS ID: /devices/pci0000:00/0000:00:02.0/0000:05:00.0 SysFS BusID: 0000:05:00.0 Hardware Class: graphics card Model: "ATI RV770 [Radeon HD 4850]" Vendor: pci 0x1002 "ATI Technologies Inc" Device: pci 0x9442 "RV770 [Radeon HD 4850]" SubVendor: pci 0x1787 "Hightech Information System Ltd."

The thing that raises my attention is that both devices use the same driver, snd_hda_intel.
If the sound is going through HDMI then the Video card that is outputting the HDMI signal will also be treated as the sound card. Given it is just forwarding the digital audio signal via HDMI it shouldn't be doing much processing though.
Another thing to check is that your playback sample rate isn't too high and matches one that can be sent over HDMI otherwise your sound card is having to convert the digital signal which it may not be good at. I don't know how to check / set that with pulse audio though.
I have no possibility to set anything in my monitor concerning sound, which is an ACER. # hwinfo --monitor 29: None 00.0: 10002 LCD Monitor [Created at monitor.125] Unique ID: rdCR.ukgc1_4VzS0 Parent ID: Ddhb.zvQlrOmSRQ8 Hardware Class: monitor Model: "R231" Vendor: ACR Device: eisa 0x0504 "R231" Serial ID: "T6GEE0012400" Resolution: 720x400@70Hz Resolution: 640x480@60Hz Resolution: 640x480@67Hz Resolution: 800x600@56Hz Resolution: 800x600@60Hz Resolution: 1024x768@60Hz Resolution: 1024x768@70Hz Resolution: 1152x864@75Hz Resolution: 1280x1024@60Hz Resolution: 1280x720@60Hz Resolution: 1920x1080@60Hz Size: 509x286 mm Year of Manufacture: 2016 Week of Manufacture: 4 Detailed Timings #0: Resolution: 1920x1080 Horizontal: 1920 2008 2052 2200 (+88 +132 +280) +hsync Vertical: 1080 1084 1089 1125 (+4 +9 +45) +vsync Frequencies: 148.50 MHz, 67.50 kHz, 60.00 Hz Driver Info #0: Max.

Mouse movement on the screen is in sync with moving the mouse. The only solution is to have the sound processing faster. -- fr.gr. member openSUSE Freek de Kruijf -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
