 |
|
Any suggestions on remapping 5.1 sound to 2.1 (ie. sterio)?
I am attempting to play the December 2022 updated version of Witcher3 and everything works except for the cut-scene voices which are non-existent. A little searching indicates that Witcher3 now expects 5.1 sound and I don't have the other channels. I am using alsa and the USB audio device to control the analog line out on the motherboard.
from 'aplay -l' and skipping the card 1 Nvidia lines. (I have no idea why there is no card 0)
| Code: | card 2: Audio [USB Audio], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 2: Audio [USB Audio], device 1: USB Audio [USB Audio #1]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 2: Audio [USB Audio], device 2: USB Audio [USB Audio #2]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 2: Audio [USB Audio], device 3: USB Audio [USB Audio #3]
Subdevices: 1/1
Subdevice #0: subdevice #0 |

Split off of Native Steam client and source game engine into its own topic, as the issue doesn't seem specific to using Steam, and it will probably get more eyes on it this way.
I believe I used something like this to force audio into the correct stereo channels for Dark Souls, which I think does or at least did something similar with no options to change it:
| Code: | pcm.correctedSurround
{
type plug
slave.pcm "device/pcm name here"
ttable
{
0.0 1 # Front Left
1.1 1 # Front Right
2.0 0.5 # Rear Left
3.1 0.5 # Rear Right
4.0 1 # Front Center
4.1 1 # Front Center
5.0 0.5 # Rear Center
5.1 0.5 # Rear Center
}
hint
{
show on # May or may not make this show up as an audio device choice in things.
}
} |

Chiitoo, Anon-E-moose thanks for the replies.
I created a ~/.asoundrc that contains the following that solves the issue:
| Code: |
defaults.pcm.!card 2
defaults.pcm.!device 0
pcm.correctedSurround
{
type plug
#slave.pcm "device/pcm name here"
slave.pcm "Audio"
ttable
{
0.0 1 # Front Left
1.1 1 # Front Right
2.0 0.5 # Rear Left
3.1 0.5 # Rear Right
4.0 1 # Front Center
4.1 1 # Front Center
5.0 0.5 # Rear Center
5.1 0.5 # Rear Center
}
hint
{
show on # May or may not make this show up as an audio device choice in things.
}
} |
Edit: That solves the issue sometimes. |
