EAPD command can be issued only on widgets that support. ALC262 has no EAPD pin caps at all. so it doesn't work like that. Instead, ALC262 (and other Realtek codecs) has a special sequence with coefficients to the vendor-defined widget. Yes, it's a black magic. Try the following sequence: 0x20 SET_COEF_INDEX 0x07 0x20 SET_PROC_COEF 0x3060 0x3060 can be different numbers like 0x3070 or 0x3050. If you set a different number, reset the coef index again (i.e. always call as a pair).
