There are 3 causes to the silence of Compaq 6530s' internal speaker:
- HP pin 0x11 always return 0xffff,ffff (pin_presence=1), which automutes the speaker at module loading time.
This is odd. Is the sense-trigger issued before reading the pin sense?
Sorry, what do you mean? The facts I explored are:
- ad1884a_hp_automute() will be explicitly called by ad1884a_hp_init()
- ad1884a_hp_unsol_event() is never called on plug events
- I tried manually execute AC_VERB_SET_PIN_SENSE then read pin sense, it takes effect on the impedance, but pin_presence still remains 1.
The fact that it returns only -1 sounds rather like a hardware issue. Or, at least, reading a wrong place or so.
BTW, could you give alsa-info.sh output on both machines?
I'm now testing 6531s. All verbs/states seem OK.
In fact for 6531s, the speaker can produce sound on fresh boot. However after a while the sound disappeared. No single write verb was executed during the time! And then I found the 0x1c trick can be applied to 6530s as well as 6531s, and magically make the speaker work by applying this patch.
--- hda: enable speaker output for Compaq 6530s/6531s
HP Compaq 6530s and 6531s internal speaker is silence or becomes silence within 1 minute after fresh boot. It is found that pin 0x1c must be set to PIN_OUT mode to make the speaker work. This is weird - line-in pin 0x1c and speaker pin 0x16 seem to be unrelated.
The codec differences before/after patch are:
