Reverse Stereo?

[kde35]

I am trying to swap the left and right side of the stereo output under Linux Mint 13 Maya. I followed this. But when I created .asoundrc with the content

Code: Select all

pcm.swapped {
    type         route
    slave.pcm    "cards.pcm.default"
    ttable.0.1   1
    ttable.1.0   1
}

pcm.default      pcm.swapped

and rebooted, just in case, as I haven't found out how to restart alsa, it has no effect. When I did

Code: Select all

pactl load-module module-remap-sink \
    sink_name=reverse-stereo \
    master=0 \
    channels=2 \
    master_channel_map=front-right,front-left \
    channel_map=front-left,front-right

then a new sink get created, but when I chose new sink as output, there was no sound. I also tried to add

Code: Select all

load-module module-remap-sink sink_name=reverse-stereo master=alsa_output.pci-0000_00_1b.0.analog-stereo  channels=2 mast
er_channel_map=front-right,front-left channel_map=front-left,front-right

or

Code: Select all

load-module module-remap-sink sink_name=reverse-stereo master=0 channels=2 master_channel_map=front-right,front-left chan
nel_map=front-left,front-right

but in either case, output to the reverse-stereo sink produced no sound. Would there be any other way to swap the right and left
stereo sound output?

inxi -Fxz | grep Audio gives

Code: Select all

inxi -Fxz| grep Audio
Audio:     Card-1: Intel 7 Series/C210 Series Chipset Family High Definition Audio Controller driver: snd_hda_intel bus-ID: 00:1b.0
           Card-2: Advanced Micro Devices [AMD/ATI] Turks/Whistler HDMI Audio [Radeon HD 6000 Series] driver: snd_hda_intel bus-ID: 01:00.1

I also tried editing /etc/pulse/daemon.conf changing the line

Code: Select all

; default-channel-map = front-left,front-right

to

Code: Select all

default-sample-channels = 2
default-channel-map = front-right,front-left

as is suggested here, but this changes nothing.

Can you switch the wires instead? That might be the easy way to do it, but it might also be the best way to do it.

Well, I would need some extension cables, certainly they wouldn't ruin me, but somehow I feel that there should be a soft-ware solution for this kind of
problem.

I think that switching the wires is the "right" way to do it, from a purely sonic and simplistic perspective.

Keep it as simple as possible. Otherwise you run the risk of seriously messing up the sound in your Linux.

One small issue. My PC is set up for multi-boot and every other OS except Linux has the channels oriented correctly. Since I installed Mint 20.2, the audio channels are reversed only in Mint????
