I've got a SBLive 5.1 Player in my system which is probed like this:

emuxki0 at pci0 dev 11 function 0: Creative Labs SBLive! EMU 10000 (audio multimedia, revision 0x07)
emuxki0: interrupting at irq 10
emuxki0: SigmaTel STAC9708 codec; 18 bit DAC, 18 bit ADC, Rockwell 3D
audio0 at emuxki0: full duplex, mmap, independent

I initialize volume and some other parameters during system startup
in "/etc/rc.local" with these commands:

mixerctl -w outputs.master=183,183 >/dev/null
mixerctl -w inputs.line=135,135 >/dev/null
mixerctl -w inputs.line.mute=off >/dev/null

I used this method with my Soundblaster PCI 128 for years succesfully.
With the SBLive! the volumes gets reset very often as soon as "mpg123"
starts. After a few rounds of the sequence described below the volume
finally stays at 183.

This problem is *not* related to any other mix application. I've
explicitly checked that.

mixerctl -w outputs.master=183,183
mpg123 -v ...
mixerctl outputs.master

None provide.
