[alsa-devel] alsa-info.sh was broken recently
by Sergey 19 Sep '14

19 Sep '14

Hello. Something was broken recently. http://www.alsa-project.org/alsa-info.sh leads to Error 404. As well as http://www.alsa-project.org/alsa-info.sh.changelog It breaks many tutorials and documentation references, e.g.: http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio.txt It also breaks the alsa-info.sh script itself attempting to update from that url. -- Sergey

[alsa-devel] Alsa Driver Scarlett
by Eugène Bandit 19 Sep '14

19 Sep '14

Hello, I've come across this earlier post from the alsa-devel mailing list : http://thread.gmane.org/gmane.linux.alsa.devel/126241/focus=126682 It deals with a kernel patch made to support some Focusrite Scarlett hardware, you can find the github project page is here : https://github.com/smilingthax/alsa-driver_scarlett I would be really interested in it being integrated into alsa. Unfortunately, it appears that the original developer of this patch cannot put any time into such a thing. Since I'm not skilled enough to perform this integration, i wanted to know if anyone was willing to work on this ? I own a Focusrite Scarlett 18i20 and can perform any test to help.

[alsa-devel] [PATCH] ASoC: max98090: Fix missing free_irq (part 2)
by Jarkko Nikula 19 Sep '14

19 Sep '14

I was blind to see interrupt was requested in codec probe instead of i2c probe when doing commit 4adeb0ccf86a ("ASoC: max98090: Fix missing free_irq") and there is still a case where interrupt is kept requested. Although not as fatal as original issue. Since codec can be reprobed while driver is loaded the subsequent max98090_probe() call will fail in interrupt request since it wasn't freed. Fix this by explicitly freeing irq in max98090_remove().

Also the same thing for v3.17-rc5 and next-20140918. So let's see if we can remove this driver too. Done on top of next-20140918.
