Hi,

I need some assistance with alc887 and amixer/alsamixer.

Please see bug post 0005090. Which explains the problem.

Very happy to provide additional information or assistance is needed

Unfortunately, I do not have the knowledge to fix the issue.

cheers lumpy

it seem that node 0x0c of alc887 has "nsteps=0" and the alsa-driver had created a volume control without any steps (i.e. min = max )

the error returned by snd_hda_mixer_amp_volume_info() cause both alsamixer and amixer fail

HDA_CODEC_VOLUME("Front Playback Volume", 0x0c, 0x0, HDA_OUTPUT),
