This allows the user some control over which sound card is used as they can set the ALSA_CARD environment variable or edit ~/.asoundrc. /* ALSA troubleshooting notes. If ALSA tries to play sound out of the wrong card or if you get an error, try setting the ALSA_CARD environment variable. For example, 'export ALSA_CARD=1' to use the second sound card detected. Or, you can use a name like ALSA_CARD=PCH or ALSA_CARD=HDMI. Use 'cat /proc/asound/card?/id' to see all options. If you have troubles with PulseAudio interfering, you can try stopping it with: systemctl --user stop pulseaudio.* */

/* ALSA troubleshooting notes.
If ALSA tries to play sound out of the wrong card or if you get an
error, try setting the ALSA_CARD environment variable. For example,
'export ALSA_CARD=1' to use the second sound card detected. Or, you
can use a name like ALSA_CARD=PCH or ALSA_CARD=HDMI. Use 'cat
/proc/asound/card?/id' to see all options.
