[alsa-devel] Thinkpad T520 (Low Volume)
2014/1/16 Axel Braun axel.braun@gmx.de
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)

thinkpad t520 was supported with CXT5066_AUTO which use cxt5066_update_speaker which check port a and port d
Do this mean thinkpad don't support surround 4.0 by dock headphone and headphone ?

ALSA: hda - Fix multi-io channel mode management
this patch change the the channel_count from 2 to 4 since there are two headphone
+ if (cfg->line_out_type != AUTO_PIN_HP_OUT) + spec->const_channel_count = max(spec->const_channel_count, + cfg->hp_outs * 2);
if you don't have docking station , the workaround is to remove those pin fix of node 0x1a and 0x1c

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
?

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

I'm using a headset from a smartphone - it is the same 3,5mm jack

works fine
try hda_analyzer to change the volume slider of those nodes 0x10 and 0x11
maybe I'm on the wrong track...but do I have to apply the diff code to the alsa source code and then rebuild the package?

yes
or

Master is set to -13dB, so this is normal.
