How to reproduce:
Try to get sound to come from the HP RP 5810 speaker using:
printf '\a'
printf '\007'
echo -e '\a'
echo -e '\007'
beep -f330 -l137 -n -f330 -l275 -n -f330 -l137 -n…etc (I have a beep tune in a shell script)
// when beep is run, it appears to run with no errors.
Actual results:
The above commands run without any complaints of missing audio device. But no sound coming from the 5810 PC internal Speakers
Beeps/terminal bells are a bit different. They are handled through the sound
servers these days, thus the PWM modulator output is disabled by default in
the HDA driver. I assume that you're running your system without the sound server.
$ modinfo snd-hda-intel | grep beep
parm: beep_mode:Select HDA Beep registration mode (0=off, 1=on)
(default=1). (array of bool)
Note that CentOS 7 have the default 0 (off) for this parameter. The
description is incorrect. Try to set this module parameter in modprobe
configuration files:
echo "options snd-hda-intel beep_mode=1" > /etc/modprobe.d/alsa-beep.conf
... and reboot
