Nvidia and mpv

[zogg]

Hey,

I have i7 CPU and till recently was using builtin video card. Everything worked smoothly except some steam games. So I switched to Nvidia GeForce GTX 980. 

I have no problems (mostly) with games and everything is working fine.

Though I have problems with playing videos with mpv player. At some point movie starts to lag and i need to pause and unpause to sync audio and video.

I have TV connected thru HDMI (both audio and video) and DVI for monitor.

using nvidia blobs 370.23 (flags are: X acpi driver gtk3 kms multilib tools uvm)

 

xorg configs: 

$ cat /etc/X11/xorg.conf.d/20opengl.conf 
Section "Files"
        ModulePath "/usr/lib64/opengl/nvidia"
        ModulePath "/usr/lib64/xorg/modules"
EndSection

 

$ cat /etc/X11/xorg.conf
#Section "Device"
#Identifier "Card0"
#Driver "intel"
#Option ?AccelMethod? ?sna?
#EndSection
Section "Device"
  Identifier "nVidia"
  Driver     "nvidia"
  Option     "NoLogo" "true"
EndSection


Section "Extensions"
Option "Composite" "Disable"
EndSection

 

in mpv.conf i tried different settings. current is :

 

vo=opengl:interpolation
video-sync=display-resample
#vo=vdpau
#[vo.vdpau]
hwdec=vdpau

 

also i have some alsa configs to be able to use both onboard plug for headphones and HDMI output as audio sources:

$ cat /etc/asound.conf
defaults.pcm.!card 1
defaults.pcm.!device 7 


$ cat ~/.asoundrc
#defaults.pcm.dmix.!rate 48000
#defaults.pcm.dmix.!format S16_LE
pcm.multi {
    type multi
    slaves.a.pcm "dmix:PCH,0"
    slaves.a.channels 2
    slaves.b.pcm "dmix:1,7"
    slaves.b.channels 2
    bindings.0 { slave a; channel 0; }
    bindings.1 { slave a; channel 1; }
    bindings.2 { slave b; channel 0; }
    bindings.3 { slave b; channel 1; }
}
pcm.both {
    type route
    slave.pcm "multi"
    ttable.0.0 1
    ttable.1.1 1
    ttable.0.2 1
    ttable.1.3 1
}
ctl.both {
        type hw
        card 1
        device 7
}
pcm.!default {
    type asym
    playback.pcm "plug:both"
    capture.pcm "hw:StudioTM,0"
}
ctl.!default {
        type hw
        card 1
        device 7
}

 

Can it be related to the alsa settings (i heard something related to the problem of audio and video sync) or any other direction/help will be appreciated.

Thanks

It is related to ALSA and downmix. If there any suggestions on how to config both headphone jack from onboard soundcard and HDMI audio at the same time and have no lags with alsa - I would be grateful.
