It would seem that both the headphone jack and the internal speaker are being driven by an amplifier outside the ALC260 which is switched on using mechanisms independent of the ALC260 chip itself. This would be the second laptop we've encountered with a similar issue - even though everything's up these two outputs refuse to produce any sound. I'll be pondering this issue over the next few days to see if there's something obvious that I've missed - perhaps there's an obscure object in the ALC260 that the test model doesn't unmute which is needed by these HP laptops. Maybe others on the list have ideas as well. Final thought for the day: could you use alsamixer to change all the pin modes to "Line-in" and then back to "Line-out" or "headphones". Then try the tests again and see if you get audio from any additional jacks or the internal speaker.
