Linux tips: Set default sound card using Pulse Audio

 Linux tips: Set default sound card using Pulse Audio

 

1) Check list of Sources:-

#  pactl list short sources

2    alsa_output.pci-0000_00_1b.0.analog-stereo.monitor    module-alsa-card.c    s16le 2ch 48000Hz    RUNNING
3    alsa_input.pci-0000_00_1b.0.analog-stereo    module-alsa-card.c    s16le 2ch 44100Hz    RUNNING

// Set default source

#  pactl set-default-source alsa_input.pci-0000_00_1b.0.analog-stereo

 

2) Check list of Inputs:-

#  pactl list short sinks

2    alsa_output.pci-0000_00_1b.0.analog-stereo    module-alsa-card.c    s16le 2ch 48000Hz    IDLE

// Set default input/sink

# pactl set-default-sink alsa_output.pci-0000_00_1b.0.analog-stereo

==================================================

Or use this method (Tested working on Linux Mint 20.1):

a)  Run the following (on working & active (Pulse Audio configuration) profile)

#   pacmd list-cards
 

index: 1

name: <alsa_card.pci-0000_00_1b.0>

active profile: <output:analog-stereo+input:analog-stereo>

b) Test the command:-

// If the following command set the profile & output correctly,

// just check the pulseaudio volume control's configuration portion,

// proceed to part c).

#   pactl set-card-profile alsa_card.pci-0000_00_1b.0 output:analog-stereo+input:analog-stereo

c) Add to /etc/pulse/default.pa (at the bottom):-

set-card-profile alsa_card.pci-0000_00_1b.0 output:analog-stereo+input:analog-stereo

 d) Reboot
