Hello!
I can’t get the sound to work on my ACER Aspire R3 N15WS. (I want to run the built-in speakers, not the HDMI!)
I don’t know what else to try… This is what I have done:
(1) aplay -L (The following devices appears too under “Setting > Audio > Output > Device”)
Lakka:~ # aplay -L
null
Discard all samples (playback) or generate zero samples (capture)
default:CARD=PCH
HDA Intel PCH, ALC255 Analog
Default Audio Device
sysdefault:CARD=PCH
HDA Intel PCH, ALC255 Analog
Default Audio Device
front:CARD=PCH,DEV=0
HDA Intel PCH, ALC255 Analog
Front speakers
surround21:CARD=PCH,DEV=0
HDA Intel PCH, ALC255 Analog
2.1 Surround output to Front and Subwoofer speakers
surround40:CARD=PCH,DEV=0
HDA Intel PCH, ALC255 Analog
4.0 Surround output to Front and Rear speakers
surround41:CARD=PCH,DEV=0
HDA Intel PCH, ALC255 Analog
4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=PCH,DEV=0
HDA Intel PCH, ALC255 Analog
5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=PCH,DEV=0
HDA Intel PCH, ALC255 Analog
5.1 Surround output to Front, Center, Rear and Subwoofer speakers
surround71:CARD=PCH,DEV=0
HDA Intel PCH, ALC255 Analog
7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
hdmi:CARD=PCH,DEV=0
HDA Intel PCH, HDMI 0
HDMI Audio Output
I tried all the settings, for example:
audio_device="default:CARD=PCH"
or
audio_device="front:CARD=PCH,DEV=0"
No one works!
(2) Available drivers are:
alsa / alsathread / tinyalsa / oss
No one works!
(3) here my log:

That “ALSA lib” & “MIDI-Error” Messages appears with any configuration.
Any ideas how can I fix the problem?
Thanks!!!
