mixer vol does not change 5.1 back speakers

[Emanuel Haupt]

hi all,

$ uname -imr
5.4-RELEASE-p1 i386 BEAVER

cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <Creative EMU10K1> at io 0xdf80 irq 21 kld snd_emu10k1 (4p/2r/0v channels duplex default)

using:
 sound.ko
 snd_emu10k1.ko

i just got myself a fancy 5.1 speaker system. unfortunately
changing master "vol" just changes the two front speakers, the middle
and the two back speakers always remain in the same volume even by
running:

$ for i in $(mixer | awk '{print $2}'); do mixer $i 0; done

just FYI, these are my mixer options:

Mixer vol      is currently set to  84:84
Mixer pcm      is currently set to  75:75
Mixer speaker  is currently set to  75:75
Mixer line     is currently set to  75:75
Mixer mic      is currently set to   0:0
Mixer cd       is currently set to  75:75
Mixer rec      is currently set to   0:0
Mixer line1    is currently set to  75:75
Mixer phin     is currently set to   0:0
Mixer phout    is currently set to   0:0
Mixer video    is currently set to  75:75

is anyone else having the same problem? if it's a bug i'm going
to send a pr.

emanuel
