Hello 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
The MoBo is an old ASUSTeK Computer Inc. M5A99X EVO (R2.0) and it has
three jacks of different colors to connect to the Logitech Z906 ¹ case:
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:
~# lspci -nnv -s 00:14.2

Clementine ² audio player seems that 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 noise 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 at all, neither from the Subwoofer. Does anybody know how
can I test the speakers of my 3D Dolby surround system? Please help.
