I have 6 Jacks at the rear panel and two at the top (one output one

input)

...

I am afraid I do not know how to switch channel mode to retask.

Also, the computer is of a certain age, and the issue has started

several month ago but I never really looked into it, so I am not sure that change in power management will be relevant has it seems quite recent.

Do the driver need a pin fixup for the digital pin or more check when assign dig out type ?

If codec has two digital pin complex with diffferent type, check whether the primary digital pin complex support DETECT

case AC_JACK_SPDIF_OUT: case AC_JACK_DIG_OTHER_OUT: if (cfg->dig_outs >= ARRAY_SIZE(cfg->dig_out_pins)) { codec_info(codec, "ignore pin 0x%x, too many assigned pins\n", nid); continue; } cfg->dig_out_pins[cfg->dig_outs] = nid; cfg->dig_out_type[cfg->dig_outs] = (loc == AC_JACK_LOC_HDMI) ? HDA_PCM_TYPE_HDMI : HDA_PCM_TYPE_SPDIF; cfg->dig_outs++; + if (cfg->dig_outs == 2) + if (cfg->dig_out_type[0] != cfg->dig_out_type[1]) + if (! snd_hda_query_pin_caps(codec, cfg->dig_out_pins[0]) & AC_PINCAP_PRES_DETECT)) + cfg-> dig_out_type[0] = HDA_PCM_TYPE_SPDIF;
