Yeah. I kind of knew. But now you can open a new thread for someone that use loppback to fix it (it's more easy with just one file). _________________ | Proverbs 26:12 |

This works now, installing alsaequal solved it, "type equal" requires it.
I will have to insert 6 channels etc. to test it fully though and see how it behaves.
But it works.

I will play with recording when I solve LADSPA, which is a priority right now.
But changing a config file just for that occasion is not really a big of a problem, for now. |

Hahaha , yeah
I'll try now btw that alsaequal with those caps plugins, maybe I can come up with something |

Problem with alsaequal is guess what ... 5.1
It says here how you define number of channels
https://github.com/bassdr/alsaequal
so
Code: |
ctl.equal {
type equal;
channels 6;
}
pcm.plugequal {
type equal;
slave.pcm "plughw:2,0";
channels 6;
}
pcm.equal{
type plug;
slave.pcm plugequal;
} |
it gives :
Code: | $ speaker-test -Dequal -c6 -l1 -twav
speaker-test 1.2.2
Playback device is equal
Stream parameters are 48000Hz, S16_LE, 6 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 32 to 87376
Period size range from 16 to 43680
Using max buffer size 87376
Periods = 4
Unable to set nperiods 4 for playback: Invalid argument
Setting of hwparams failed: Invalid argument

That's normal. Most users use only stereo (and most use headphones too).
The github issue is disabled for the repo and don't have any way of reach the owner of the fork. So no support too.
EDIT: There is a "successor of LADSPA", the "media-libs/lv2" (http://lv2plug.in). Maybe there is something better there (like the eq10q). But have to found how to use it first. _________________ | Proverbs 26:12 |

Even tried to patch the alsaequal and change the number of channels that way, that way there's no error with speaker-test but channels are wrong.
Code: | --- a/ctl_equal.c-org 2020-03-11 19:04:01.586892606 +0100
+++ b/ctl_equal.c 2020-03-11 19:11:12.473502205 +0100
@@ -167,7 +167,7 @@
const char *controls = ".alsaequal.bin";
const char *library = "caps.so";
const char *module = "Eq10";
- long channels = 2;
+ long channels = 6;
const char *sufix = " Playback Volume";
int err, i, index; |
I'll remove alsaequal and try something else.
Nice find @ff11 about lv2, I'll take a closer look now. |

I has taken a look, but this ins't very clear.You will have to read the documentation of "freesurround-alsa".
Well, unfortunately the lv2 doesn't seem to work with pure alsa.
If you like things like this, then i will recommend the change to JACK,
and the use of "Carla" to load and manager the plugins: https://github.com/falkTX/Carla _________________ | Proverbs 26:12 |

I tested freesurround, it makes it worse in my case, instead of upmixing to 5.1 it makes everything to 2.1
That made me thinking about upmix alsa plugin and why it doesn't work with LADSPA, so I did testing without LADSPA and it doesn't upmix anything, having it there or not is completely the same and doesn't make a difference.
I was thinking about JACK but it would be too much for me right now, maybe some day.
Kinda getting used to living without that sc4 plugin , it's not that bad without it like it used to be few years back, maybe libraries changed and it's better now or it's worse in pulseaudio and somehow better in pure alsa.
Easy to test with pulseuadio without LADSPA but I'm not in mood for testing that now.
Some sources are too low without it, like if I play some music and notification comes with sound (it plays wav file actually) I can barely hear it, with sc4 ladspa plugin everything was equalized to the same level.
Well... it is what it is... LADSPA is definitely doing it's thing with pure alsa, upmix should take that 2.0 output from it and make it 5.1 but it doesn't.
I'll try to look for maybe some other upmix plugin out there, I don't know... |

I think you will have to use alsa route for this. like:
Code: |
# 2.0 to 4.1 mirrors the front speakers to the rear speakers, and combines the two
pcm.20to51 {
type route
slave.pcm surround51
slave.channels 6
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
ttable.0.4 0.5
ttable.1.4 0.5
}

No, it's the same like it was with regular upmix.
After LADSPA is involved the sound comes only from front-left and front-right speakers.
Interestingly, Kodi in that case doesn't see a regular device, only shows Loopback devices.
And doesn't produce audio at all.
Weird stuff! |

Again the same.
I feel there's nothing that could be done.
Either some new (more recent) plugins which are doing the similar thing or I don't know what, it's just not doable maybe.
I mean I understand that majority of people have stereo speakers/headphones , but having 5.1 speakers or better isn't abnormal ffs |

Starting to hate this
But still the same.
I read Arch wiki just now, wanted to learn more about speex thingy, what more options are there with it etc.
https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture#High_quality_resampling
and there's a section about LADSPA , mbeq actually, which says what is already known but I guess speaks enough (it can't be done with 5.1)
Quote: | Note: This method requires the use of a LADSPA plugin which might be CPU intensive during playback. In addition, this was made with stereophonic sound (e.g. headphones) in mind. |
I'm using your config with disabled ladspa and I'm happy with it for now, I'll stay with it, it's not that bad
I appreciate your help but I think it's best to forget about LADSPA in this scenario, I think I will |

Well, this thing is a bug on the alsa and LADSPA integration. If you want to report: https://alsa-project.org/wiki/Bug_Tracking
On https://wiki.archlinux.org/index.php/Talk:Advanced_Linux_Sound_Architecture we have:
Code: | linear: 0.01s user 0.04s system 0% cpu 8.138 total
samplerate: 0.38s user 0.01s system 4% cpu 8.147 total
speexrate: 0.24s user 0.01s system 2% cpu 8.137 total
samplerate_medium: 0.60s user 0.01s system 7% cpu 8.149 total
speexrate_medium: 0.32s user 0.06s system 4% cpu 8.143 total
samplerate_best: 1.36s user 0.01s system 16% cpu 8.204 total
speexrate_best: 0.79s user 0.01s system 9% cpu 8.166 total
|
So you can try the "speexrate_best" with just a little more cpu.
EDIT: And if you want improve even more, then you can change the "rate" that the mixing is working form 48000 (48kHz) to 96000 (96kHz). _________________ | Proverbs 26:12 |

The only thing that annoys me is that it works in pulseaudio, but whatever...
Good tips, I'll do that for sure and see the impact (if there is any noticeable) , that Arch wiki says medium is fine, quality is not that visible with best but cpu impact is, something like that. |

Yep! You can get more changing to 96 kHz and 32bit (instead of the 16bit).
Code: | rate 96000
format S32_LE

I tried, well , speexrate_best is cpu intensive and I can't notice much difference, went back to medium.
On the other hand, format32_LE and 96000 seems to be better indeed.
I modified your conifg and placed those in this section, removed from other places other instances.
pcm.onboard_card {
type hw
card 2
format S32_LE
rate 96000
} |

Good! You can always test using (while playing something):
Code: | $ cat /proc/asound/card0/pcm0p/sub0/hw_params |
