Under Manjaro 18.1.5 the sound has been "tinny" compared to the Windows experience and I have to crank up the volume much louder to get a good sound experience.
-
I have a laptop with built-in Front Left & Right speakers and a subwoofer speaker on the bottom.
-
In another post, I've seen that the
aplay --list-pcmscommand lists the possible Pulse Code Modulation devices:null Discard all samples (playback) or generate zero samples (capture) jack JACK Audio Connection Kit default Default ALSA Output (currently PulseAudio Sound Server) 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 ...(some irrelevant HDMI stuff deleted)
-
using
speaker-testit looks like I'm only using the front speakers:speaker-test --device=front --channels=2 --nloops=1 --test=sine
The question is: How do I change the default from the first bold item to the second bold item? (Front Left&Right speakers to 2.1 surround)?
Some more info:
-
The 5.1 surround system that I deleted from the above output seems to be linked to the nVidia HDMI ports, not to the internal speakers...
-
The
inxi --audiooutput is:Audio: Device-1: Intel CM238 HD Audio driver: snd_hda_intel Device-2: NVIDIA GP104 High Definition Audio driver: snd_hda_intel Sound Server: ALSA v: k5.4.17-1-MANJARO -
I Can't find anything in Audio settings in the GUI:
-
the HDMI surround can be seen in the alsamixer devices, but the surround2.1 cannot:
