[alsa-devel] volume adjust doesn't work after calling many times

hi, all,

after I use UI interface with pavucontrol to tune output devices volume rapidly many times, the volume adjust seems doesn't work! error occur in dmesg:

[ 568.807025] ALSA sound/pci/hda/hda_intel.c:716: azx_get_response timeout, switching to polling mode: last cmd=0x001f000a [ 569.808026] ALSA sound/pci/hda/hda_intel.c:755: hda_intel: azx_get_response timeout, switching to single_cmd mode: last cmd=0x001f000a

realtek ALC888 codec. alsa version 1.0.23

attached the alsa-info output.

any comment?

BR, Keyon
