Public bug reported: Hello,
my computer is connected to my TV screen with HDMI. I'm using HDMI displayport audio out in pulseaudio. I hear crackling and echoing. If I use this workaround: echo '# add support for intel audio options snd-hda-intel vid=8086 pid=8ca0 snoop=0' >> /etc/modprobe.d/alsa-base.conf it works but after several minutes I have an important delay between video and audio. Thank you for your help. LGDN.
