[alsa-devel] HDA regression on Fujitsu S7020 laptop (ALC260 codec)

> - there is no alsamixer control for the internal speaker. I have a "PCM"
volume control which appears to do nothing. Previously there was a speaker
control, the PCM control affected every output (from memory), as did the
master volume.

Take a look at function alc_get_line_out_pfx

Most likely lack of speaker pin complex

> no audio comes out of the internal speaker regardless of the "auto mute"
setting.

>- there are no pin mode (re-tasking) controls for the mic or headphone
jack in alsamixer. On this laptop the mic jack should have various bias
options as well as line-in. The headphone jack should include headphone
(aka output amplifier on), line-out (output amplifier off), line-in and mic
options.

All retaskable jacks support impedance measurement

Try hda-verb SET_PIN_SENSE and GET_PIN_SENSE to find out the impedance and
PD bit of different jacks

E8020 has same PCI SSID and codec SSID as your S7020

It has a spdif/headphone jack

Do the driver need to disable GPIO since your previous  Fujitsu model have
this init verb ?
