same problem on a ThinkPad T520, sound volume is way too low - watching movie via loudspeakers is fairly impossible. Any hint you could give me?
post the output of alsa-info.sh , there is a bug in alsa-driver which
treat
dock headphone and headphone to support surround 4.0
you get low volume because Amp Out vals are 0x3d instead of 0x4a but speaker volumes are at 100% (0dB)
Can I influence that from the running system, e.g. by echo 0x4d > ....
refer to user manual, it seem that both headset and headphone are supported but you cannot use conventional mic with this combo audio jack
are you using headset or headphone ?
do headset mic work or not ?
try hda_analyzer to change the volume slider of those nodes 0x10 and 0x11
?

if you don't have docking station , the workaround is to remove those
pin
fix of node 0x1a and 0x1c
I dont have a docking station - but I have no clue what I should do here...
the easy way is to use model=nofixup since your bios does not have dock headphone and dock mic pins default but this also remove mic mute led

just remove dock mic and dock hp from cxt_pincfg_lenovo_tp410
/* ThinkPad 410/420/510/520, X201 & co with cxt5066 */ static const struct cxt_pincfg cxt_pincfg_lenovo_tp410[] = { { 0x19, 0x042110ff }, /* HP (seq# overridden) */ - { 0x1a, 0x21a190f0 }, /* dock-mic */ - { 0x1c, 0x212140ff }, /* dock-HP */ {} };
there are dock stations which only has combo jack for the dock headset and some have dock mic and dock headphone jacks
as some notebooks have dual headphone jacks , should those headphone pin put in multi out with mic jack retasked to support 5.1
