After work with a multitouch screen for the BeagleBone Black, now I just
want to play audio/sounds through the HDMI connection as the multitouch
screen has a speaker.
First of all, I just copied an audio sample, and try to reproduce it by
'vlc', but next message is shown:
"*Audio output failed. The audio device "default" could not be used.
No such file or directory*."
Then, I have installed next tools:
'alsa-base', 'alsa-utils', 'alsa-tools', 'alsamixergui'
But, when I tried to launch 'alsamixergui', the next message is shown:
"*alsamixer: function snd_ctl_open failed for default: No such file or
directory*"
And at "/etc/modprobe.d/alsa-base.conf", the content is:
* # autoloader aliases*
* install sound-slot-0 /sbin/modprobe snd-card-0*
* install sound-slot-1 /sbin/modprobe snd-card-1*
* install sound-slot-2 /sbin/modprobe snd-card-2*
* install sound-slot-3 /sbin/modprobe snd-card-3*
* install sound-slot-4 /sbin/modprobe snd-card-4*
* install sound-slot-5 /sbin/modprobe snd-card-5*
* install sound-slot-6 /sbin/modprobe snd-card-6*
* install sound-slot-7 /sbin/modprobe snd-card-7*
* # Cause optional modules to be loaded above generic modules*
* install snd /sbin/modprobe --ignore-install snd && { /sbin/modprobe
--quiet snd-ioctl32 ; /sbin/modprobe --quiet snd-seq ; : ; }*
* install snd-rawmidi /sbin/modprobe --ignore-install snd-rawmidi &&
{ /sbin/modprobe --quiet snd-seq-midi ; : ; }*
* install snd-emu10k1 /sbin/modprobe --ignore-install snd-emu10k1 &&
{ /sbin/modprobe --quiet snd-emu10k1-synth ; : ; }*
* # Keep snd-pcsp from beeing loaded as first soundcard*
* options snd-pcsp index=-2*
* # Keep snd-usb-audio from beeing loaded as first soundcard*
* options snd-usb-audio index=-2*
* # Prevent abnormal drivers from grabbing index 0*
* options bt87x index=-2*
* options cx88_alsa index=-2*
* options snd-atiixp-modem index=-2*
* options snd-intel8x0m index=-2*
* options snd-via82xx-modem index=-2*
Moreover, I have try with next commands:
'alsamixer -c 1 (2, 3... 7)'
Having next output:
"*invalid card index: 1*"
*Is there any way to reproduce any sound (*.midi, *.wav, *.mp3...) through
hdmi easily*?
