Laptop sound should work in standalone mode by default - i.e. if laptop uses analogue sound for its built-in speakers then the alsa default should be analogue sound.
The above notwithstanding, analogue sound should work without needing to load the i915 kernel driver.
For a smart automation, use PulseAudio. It's exactly for such a purpose.
The kernel driver assigns each device just in the order how they are enumerated. In the case of HD-audio, it's the order of PCI devices. It's nothing different from any other PCI drivers.
OK, but I should not have to add bloat like pulseaudio in order to have basic sound functionality.
For getting the basic sound functionality, you have to set up something. You're asking the high-level automation, hence you need something like PA.
I'm not asking for high level automation, I'm asking that when I boot my laptop with alsa the built-in speakers work by default
Your machine has multiple audio devices, thus you have to prioritize the device to pick up. It's already a high level decision that the kernel doesn't care as default, thus it requires either a high-level automation or some manual adjustment in user-space.
You're asking a simple thing, but it's not simple as you think.
I don't say that it's simple, but I believe it is a reasonably expectation.
Of course, you're free to reimplement a wheel if you don't like PA. A similar thing can be achieved just by delaying the sound driver module loading at udev level, or dynamically evaluating the priority per PCI ID, at udev and assigning the index appropriately there. (Just an idea, though.)
You also don't mention why I should have to load a graphics driver (i915) in order to get analogue sound? That makes no sense at all...
The lack of i915 influences on the index assignment since the HDMI codec driver probe fails without i915. It's the reason why the secondary HD-audio codec appears as the first, eventually it's the analog audio output in your case.
I do not use the i915 driver at all - as far as I know, it still has the "pipe state doesn't match" bug - Xvesa doesn't require it and I use the modesetting driver with Xorg (since after more than a year we're still waiting for a stable xf86-video-intel).
How do you run modesetting X driver without i915 driver?
You appear to be saying that, even if I work from the console prompt, I need to load the unneeded (and buggy) i915 driver in order to have analogue sound.
No, you seem to be mixing up the cause and the result.
You really should check why the audio doesn't work when you don't use i915. As already mentioned, it influences the probe order, as HDMI audio device probe fails without i915. At least, it works as is, if you're using the latest kernel.
If it still doesn't work, report it properly with certain logs.
