I think this problem is a variation on the "under-enumeration" discussion which was held earlier. https://lists.freedesktop.org/archives/pulseaudio-discuss/2010-August/007545.html ftp://download.nvidia.com/XFree86/gpu-hdmi-audio-document/gpu-hdmi-audio.html#_under_enumeration_of_hdmi_devices I think, currently, we do not have any other solution than to call 'load-module module-alsa-sink' if we want more than 1 sink on a card. In my opinion, this is hack-ish since the PulseAudio documentation itself mentions that this module should (almost) never be called manually. kind regards, Lode On Fri, May 27, 2016 at 4:11 PM, Lode Cools <lode.cools1 at gmail.com> wrote: > Hello, > > I have a particular audio card which provides both analog and HDMI output. > > CARDINFO: > CARDINFO{id}="PCH" > CARDINFO{card}="0" > CARDINFO{driver}="HDA-Intel" > CARDINFO{name}="HDA Intel PCH" > CARDINFO{longname}="HDA Intel PCH at 0xdf140000 irq 127" > CARDINFO{mixername}="Intel Skylake HDMI" > CARDINFO{components}="HDA:10ec0283,80862063,00100003 > HDA:80862809,80860101,00100000" > sysfs: > ATTR{class}="0x040300" > ATTR{driver}="snd_hda_intel" > ATTR{vendor}="0x8086" > ATTR{device}="0x9d70" > ATTR{subsystem_vendor}="0x8086" > ATTR{subsystem_device}="0x2063" > > Both outputs are working fine and I can play audio on both outputs > independently. > (eg.
