 Posted: Wed Dec 18, 2019 1:01 am Post subject: error opening a sound device |
 |
|
If i try to use alsa in any application I usually get the following error:
ALSA Error: snd_pcm_hw_params(alsa_pcm, hw_params) Invalid argument
Error opening a sound device.
this error specifically is from mednafen, but i always get the snd_pcmhw_params from other programs, pulseaudio works fine.
kerenl config:

my sound device does not show up in lspci but I have the following modules auto loaded:

Adel Ahmed,
Please post the content of /proc/asound/devices
What sound output are you trying to use HDMI, analogue ...
All these modules look a bit scary.
Please post your too.

Coming from Ubuntu forum.
In the sound settings of mednaffe(GUI version) add this string instead of "default" : "sexyal-literal-default"
From Forum:
"ALSA NOTE: When using the alsa driver, the "default" translates to "hw", not "default", before being sent to the ALSA API. This is necessary because ALSA's "default" audio device has very poor buffering control capabilities. If you really want to use ALSA's "default" device, use "sexyal-literal-default". |
