#
# HOW TO IDENTIFY YOUR SOUND CARDS, SINKS, SOURCES, AND PROFILES
# ---------------------------------------------------------------
#
# 1. LIST CARDS (to find CARD name and available PROFILES):
#      pactl list cards
#    Look for "Name:" under each card entry — that is your CARD value.
#    Under "Profiles:" find the profile you want (e.g. "Analog Stereo Duplex").
#    The profile key (left of the colon) is your PROFILE value.
#    Example:
#      Name: alsa_card.pci-0000_00_1f.3
#      output:analog-stereo+input:analog-stereo: Analog Stereo Duplex
#
# 2. LIST SINKS (to find SINK name and OUTPUT_PORT):
#      pactl list sinks
#    Look for "Name:" — that is your SINK value.
#    Under "Ports:" find the port for speakers/headphones — that is OUTPUT_PORT.
#    Example:
#      Name: alsa_output.pci-0000_00_1f.3.analog-stereo
#      analog-output-speaker: Speakers
#
# 3. LIST SOURCES (to find SOURCE name and INPUT_PORT):
#      pactl list sources
#    Ignore monitor sources (names ending in .monitor).
#    Look for "Name:" on a real input — that is your SOURCE value.
#    Under "Ports:" find the mic port — that is INPUT_PORT.
#    Example:
#      Name: alsa_input.pci-0000_00_1f.3.analog-stereo
#      analog-input-internal-mic: Internal Microphone
#
# 4. QUICK SUMMARY commands:
#      pactl list cards   | grep -E 'Name:|active profile|Profiles'
#      pactl list sinks   | grep -E 'Name:|Ports' -A5
#      pactl list sources | grep -E 'Name:|Ports' -A5
# ---------------------------------------------------------------
