Unknown hardware: "HDA-Intel" "Realtek ALC259" "HDA:10ec0269,102802da,00100100" "0x1028" "0x02da"
Hardware is initialized using a guess method

tweaking 0x21 (as suggested in the patch linked by the original reporter) with HDAAnalyzer does indeed allow sound to be heard.

Note: alsamixer reports the affected channel as line out.
Note2: sound will work if line out is MUTED. state is inverted.
