I have just upgraded my Debian Jessie computer to a

Searching for "Linux alsa ALC887 low volume" shows you are not alone, if
that makes it less painful.
Some links suggest that the alsa driver for this Realtek codec has
issues. Are you running the latest kernel in Jessie (3.12) ?
Have you ever had sound from this motherboard?
Alsamixer might not be able to access to volume controls for the card.
Maybe trying the following will shed some light:
$ amixer -c0 controls | grep -i volume
<...>
numid=20,iface=MIXER,name='Master Playback Volume'
<...>
$ amixer -c0 cget numid=20
numid=20,iface=MIXER,name='Master Playback Volume'
; type=INTEGER,access=rw---R--,values=1,min=0,max=64,step=0
: values=53
| dBscale-min=-64.00dB,step=1.00dB,mute=0
So, here we have master volume set to about 80% ( = 53/64)
You can crank it that up like this:
$ amixer -c0 cset numid=20 100
numid=20,iface=MIXER,name='Master Playback Volume'
; type=INTEGER,access=rw---R--,values=1,min=0,max=64,step=0
: values=64
| dBscale-min=-64.00dB,step=1.00dB,mute=0
Check the other volume setting, too.
Any change?
