[alsa-devel] No sound for a rather old laptop (ALC260).
Hello, list.
I own a rather old laptop which features a snd_hda_intel soundcard, with a ALC260 chipset.
I know it works when using rather old kernels (Debian 7, for example), and when I was using Ubuntu 12.04 I could even download the "driver" from Realtek and compile from sources. However, after updating to newer releases (kernels 3.9 and beyond), I lost the ability to compile the module by hand (VERSION.H missing).
For older kernels I could try some "model=xxx" combinations but as far as I see from hda_codec.c, ALC260 doesn't feature such parameter anymore (N/A).
When my laptop starts up it make a few clicks and cracks (just when my Fedora initializes the module) but no sound afterwards. I have cranked every alsamixer slider to maximum but the most I get is a "very far far away sound, with a lot of skews and clicks).
I already have an alsa-info.txt file to debug, may I post it here?
Thanks,

Please attach in your post. (But maybe better to compress so that it won't hit the max size of ML.) Also, at best, take alsa-info.sh from the working state with the old kernel, so that we can compare directly.
thanks,
Takashi

Many thanks, Takashi.
I've tested a Debian 6 live image and my soundcard runs fine, so I can tell my soundcard works.
Attached are alsa-infos from kernel 2.6 (which works) and 3.14 (Fedora 20, which doesnt work).
