#269109 — speaker-test: no correct sound output on LFE and others speakers

Hi everyone,

Basically I've the same issue described here:
https://askubuntu.com/questions/1180389/speaker-test-returns-all-6-channels-to-front-speakers

The speaker-test program is provided by the alsa-utils package. I'm 
using Debian 12 Bookworm, I've no ~/.asoundrc file. My 
/proc/asound/cards returns:

~$ cat /proc/asound/cards
  0 [SB             ]: HDA-Intel - HDA ATI SB
                       HDA ATI SB at 0xfe400000 irq 16
  1 [NVidia         ]: HDA-Intel - HDA NVidia
                       HDA NVidia at 0xfe080000 irq 57

I've 5.1 speakers the LOGITECH Z906 audio system plugged to the PC via 3 
jacks (left/right), (Center/Subwoofer), (Rear left/ Rear right).

Clementine ¹  audio player seems it works well, but I'm unsure that the 
sound go to the correct speaker.

The issue is that speaker-test doesn't play sound to the correct 
speaker. If I run:

~$ speaker-test -Dplug:surround51 -c6 -s3 -f75

speaker-test 1.2.8

Playback device is plug:surround51
Stream parameters are 48000Hz, S16_LE, 6 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 349504
Period size range from 32 to 174752
Using max buffer size 349504
Periods = 4
was set period_size = 174752
was set buffer_size = 349504
   - Front Right

The sound comes from (Center), (Front right), (Rear left) and (Rear 
right) speakers instead (Front right) only. If I run:

~$ speaker-test -Dplug:surround51 -c6 -s6 -f75

speaker-test 1.2.8

Playback device is plug:surround51
Stream parameters are 48000Hz, S16_LE, 6 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 349504
Period size range from 32 to 174752
Using max buffer size 349504
Periods = 4
was set period_size = 174752
was set buffer_size = 349504
   - LFE

I've no sound from the Subwoofer. Does anybody know how can I test the 
speakers of my 3D Dolby surround system? Please help.

I assume your cabling is right and your SB soundcard has surround out
(3 jacks as you describe it, and not mic and line out for instance). The labels
on the jacks would confirm that, so would the user manual of your motherboard or
sound card.

What's bothering me is that you get sound from multiple speakers while
instructing out on only one.

The usual issues of these setups with surround analog out are:
- channel mapping issues (driver/hardware mismatch)
- software downmixing to stereo

There are other usual issues with surrount digital out but this is not
your setup.

You can have a look at [1] for software fixes on this.

The MoBo is an old ASUSTeK Computer Inc. M5A99X EVO (R1.0) and it has 
three jacks of different colors to connect to the Logitech Z906 case, 
there aren't labels, only colored jacks: Orange, Black and Lime there is 
also a Gray jack for "Side speakers" so the hardware support up to 
Surround 7.1 in addition it also have an optical S/PDIF out port unused.
The audio device is:

The link you posted it shows rather outdated fixes, it talked about 
Jackd daemon and surround, but I have pulseaudio daemon, maybe I've 
pulseaudio daemon misconfiguration, I tried what suggested here:

https://askubuntu.com/a/1304054

but unluckily  it doesn't work, this is what's enabled in 
/etc/pulse/daemon.conf:

~$ grep -v "^#\|^;\|^[[:space:]]*$" /etc/pulse/daemon.conf
remixing-produce-lfe = yes
remixing-consume-lfe = yes
lfe-crossover-freq = 80

and this is what's in the log after a reboot:

~# journalctl -b | grep pulseaudio
mag 01 14:57:28 itek systemd[1254]: Listening on pulseaudio.socket - 
Sound System.

any clue? Thank you very much

My understanding is that pulseaudio uses alsa for kernel interface and
that speaker-test uses alsa directly. So if one cannot get speaker-test
to sound right, it cannot work with pulseaudio. That why I suggest workarounds
in alsa conf (asoundrc).

I tried several configurations of ~/.asoundrc in these days but nothing 
works with "speaker-test". Well some configurations let "aplay" to use 
rear-left, rear-right, front-center speakers but "speaker-test" never 
sends sound to front-center, rear-left, rear-right and LFE with this 
command:

~$ LC_ALL=C speaker-test -c 6 -D surround51 -t wav

speaker-test 1.2.8

Playback device is surround51
Stream parameters are 48000Hz, S16_LE, 6 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 349504
Period size range from 32 to 174752
Using max buffer size 349504
Periods = 4
was set period_size = 174752
was set buffer_size = 349504
  0 - Front Left
  4 - Front Center
  1 - Front Right
  3 - Rear Right
  2 - Rear Left
  5 - LFE
Time per period = 21.908826
  0 - Front Left
^C 4 - Front Center
Transfer failed: Bad address

In place of "surround51" I've set the pcm.XXXXX  specified in 
~/.asoundrc trying so several configurations.
Just now, checking the ALSA configuration in /etc/alsa/conf.d/ I found 
the 99-pulse.conf file:

~# cat /etc/alsa/conf.d/99-pulse.conf
# PulseAudio alsa plugin configuration file to set the pulseaudio plugin as
# default output for applications using alsa when pulseaudio is running.
hook_func.pulse_load_if_running {
         lib "libasound_module_conf_pulse.so"
         func "conf_pulse_hook_load_if_running"
}

@hooks [
         {
                 func pulse_load_if_running
                 files [
                         "/usr/share/alsa/pulse-alsa.conf"
                 ]
                 errors false
         }
]

Does Debian use Pulseaudio daemon as default output for ALSA 
applications? Could it be a Pulseaudio misconfiguration? Should I try to 
uninstall it or how can I stop Pulseaudio? If I do "killall pulseaudio" 
it re-spawns immediately and "systemctl" doesn't work:

~# systemctl stop pulseaudio
Failed to stop pulseaudio.service: Unit pulseaudio.service not loaded.

Any help it's very appreciated, thanks in advance.

My hypothesis: speaker-test outputs directly to ALSA (kernel) but ALSA redirects
to pulseaudio (the 99-pulse.conf file) and pulseaudio Output profile is stereo.
Therefore, pulseaudio downmixes 5.1 to stereo. That would explain why only
front-left and front-right output sound.

To confirm, you can either:
- move away that 99-pulse.conf file so that speaker-test use directly and only
  ALSA
- configure pulseaudio output profile for surround5.1 (you can use command line
  $ pacmd set-card-profile 0 output:output:analog-surround-51 or
  pavucontrol (graphical)

> ~# systemctl stop pulseaudio

pulseaudio is usually a *user* service and socket activated (starts automatically
if some app wants to use it). To stop it, the following should work:
$ systemctl --user stop pulseaudio.socket  # stop the socket to prevent auto start
$ systemctl --user stop pulseaudio.service # stop the daemon

Cheers,

Alex

I solved by buying a Toslink (S/PDIF) optical cable, and using thus the 
"Surround 5.1 Digital output" and unplugging the three jacks analog 
cable. Now speaker-test works nicely:

~$ speaker-test -c6 -l1 -twav

speaker-test 1.2.8

Playback device is default
Stream parameters are 48000Hz, S16_LE, 6 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 32 to 349525
Period size range from 10 to 116509
Using max buffer size 349524
Periods = 4
was set period_size = 87381
was set buffer_size = 349524
  0 - Front Left
  4 - Center
  1 - Front Right
  3 - Rear Right
  2 - Rear Left
  5 - LFE
Time per period = 8,720806

maybe it was a hardware issue with the DAC of my Logitech Z906, it seems 
that with the three jacks analog cable it downmix to stereo, thanks anyway.
