[alsa-devel] More notes on HD-audio driver
Hi,
per popular demand, I wrote a brief document more about HD-audio driver. It's now found in sound git tree as Documentation/sound/alsa/HD-Audio.txt. The git tree is: git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git
You can get the text from web: http://git.kernel.org/?p=linux/kernel/git/tiwai/sound-2.6.git;a=blob_plain;f...
A PDF file is found at: http://ftp.kernel.org/pub/linux/kernel/people/tiwai/docs/HD-Audio.pdf
Comments, corrections and additions are appreciated.
thanks,
Takashi

Thank you for this. I found it informative and helpful.
Maybe it could be placed on the wiki or sent to the alsa-user list once a month as "how to troubleshoot hd audio"?

Putting Wiki is a good idea. I'm not sure whether it'd be better to put the text into Wiki or to put a link to the above URL, though...

If it isn't going to change a lot, it would be better to put the full text in the wiki. But if it is going to change a lot, a short description and a link would be better. I'm thinking of the difficulty of maintaining it in lots of places (a link, the pdf, the wiki).

I think the link would be enough. Syncing contents with Wiki isn't always so trivial.

+1 for that opinion!
duplicate 'authoritative' content is frequently a source of great confusion.
Please limit this to one doc in one location and propogate links to same from whoever needs to point someone to it.
that's why we haz intrwbz. :-)
just my us$0.02;

Nice. really interesting, and hope it will be helpful to both users and developers.
Few suggestions: * If no model option gives you a better result, and you are a touch guy to fight again the evil -- grammar/spelling errors, I would restate it as "If no model option gives you a better result, and you are a tough guy and want to fight against evil" * Maybe you should add codecgraph to the utils list - http://helllabs.org/codecgraph/ * Add links to codec manafacturers (perhaps even their documentation for HDA codecs), like Realtek, IDT, Analog Devices etc.
Keep up the great work!

Few suggestions:
- If no model option gives you a better result, and you are a touch
guy to fight again the evil -- grammar/spelling errors, I would restate it as "If no model option gives you a better result, and you are a tough guy and want to fight against evil"
Fixed.
- Maybe you should add codecgraph to the utils list -
Added.
- Add links to codec manafacturers (perhaps even their documentation
for HDA codecs), like Realtek, IDT, Analog Devices etc.
This would be nice even on Wiki or other information sources, too... Any pointers?
BTW, the source text of the document is in sound-2.6.git tree, so if you have a fix or a suggestion, please create a patch just like for the kernel code. It'd make easier to merge :)
Thanks!

Thanks for this document! In the Power-Saving section, the path /sys/modules/snd_hda_intel/parameters/power_save seems actually to be /sys/module/snd_hda_intel/parameters/power_save in 2.6.28-rc7 (no s in module).

Thanks, it's indeed a typo. Fixed now.
