[pulseaudio-discuss] ALSA sink enumeration and multiple devices/subdevices

2010-08-23 Thread Stephen Warren
Recent NVIDIA GPUs include an audio controller that hosts a number of different ALSA PCM objects. For example, consider the following output from aplay -L: hdmi:CARD=NVidia_1,DEV=0 HDA NVidia, NVIDIA HDMI HDMI Audio Output hdmi:CARD=NVidia_1,DEV=1 HDA NVidia, NVIDIA HDMI HDMI

2011-05-25 Thread Stephen Warren
(starting a new cross-mailing-list thread following some small discussion on this topic on alsa-devel) Background: Many recent graphics cards support sending an audio stream over HDMI or DisplayPort. This is supported by an HD-audio controller built into the graphics card. It'd be nice if
