It seem that multistreaming is not officially supported by pulseaudio. However it is possible to add the independent headphone (device 2) of snd-hda-intel by loading module-alsa-sink device=0,2 tsched=1 AFTER module-udev-detect in /etc/pulse/default.pa "Independent HP" switch must turn on before pulseaudio is running, otherwise PA 's default-sink and default-sink become auto-null when device 2 cannot be opened by module-alsa-sink. if your BIOS allow you to change the Front Audio Panel to AC97 instead of HDA in order to disable the jack detection and alsa-driver 's automute feature , also you may need to fix the paths to prevent pulseaudio mute and set the volume of the speakers to minimum when the headphone is plugged in. Does anyone know how to modify the paths/port for the front panel independent headphone so that it won't mute the rear panel audio jack when headphone is plugged ? Although pavucontrol can switch the audio stream to the sink#2 and sink#2 can be selected sound setting, still cannot use pulse plugin to select this special sink#2 pcm.pulse2 { type pulse device "2" } aplay -Dpulse2 test.wav Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo ALSA lib pcm_pulse.c:750:(pulse_prepare) PulseAudio: Unable to create stream: No such entity aplay: set_params:1145: Unable to install hw params: Sink #2 State: SUSPENDED Name: alsa_output.hw_0_2 Description: Built-in Audio Driver: module-alsa-sink.c Sample Specification: s16le 2ch 44100Hz Channel Map: front-left,front-right Owner Module: 8 Mute: no Volume: 0: 100% 1: 100% 0: 0.00 dB 1: 0.00 dB balance 0.00 Base Volume: 100% 0.00 dB Monitor Source: alsa_output.hw_0_2.monitor Latency: 0 usec, configured 0 usec Flags: HARDWARE DECIBEL_VOLUME LATENCY Properties: alsa.resolution_bits = "16" device.api = "alsa" device.class = "sound" alsa.class = "generic" alsa.subclass = "generic-mix" alsa.name = "AD198x Headphone" alsa.id = "AD198x Headphone" alsa.subdevice = "0" alsa.subdevice_name = "subdevice #0" alsa.device = "2" alsa.card = "0" alsa.card_name = "HDA Intel" alsa.long_card_name = "HDA Intel at 0xff9f4000 irq 45" alsa.driver_name = "snd_hda_intel" device.bus_path = "pci-0000:00:1b.0" sysfs.path = "/devices/pci0000:00/0000:00:1b.0/sound/card1" device.bus = "pci" device.vendor.id = "8086" device.vendor.name = "Intel Corporation" device.product.name = "82801H (ICH8 Family) HD Audio Controller" device.form_factor = "internal" device.string = "hw:0,2" device.buffering.buffer_size = "352800" device.buffering.fragment_size = "176400" device.access_mode = "mmap+timer" device.description = "Built-in Audio" device.icon_name = "audio-card-pci" Formats: pcm
