Could you briefly explain which function is > responsible to set that pointer and when it should happen? Since the aic26 is an SPI device, it is first probed (as you found) in the aic26_spi_probe() function. On my platform, the connection between the codec and the bus driver is described in an OF Flattened Device Tree and it uses the snd-of-simple driver to match the codec and platform drivers. So, the codec_data value is pass via the of_snd_soc_register_codec() function. I don't know the best way for your fabric driver to find the aic26 spi device. It probably should use bus_find_device() and dev_get_drvdata() to resolve to the value that codec_data should be set to. g. -- Grant Likely, B.Sc., P.Eng. Secret Lab Technologies Ltd.

[alsa-devel] Testers wanted: New SB X-Fi driver
by Takashi Iwai 19 May '09

19 May '09

Hi, after some communications with Creative, I finally got a mergeable version of their X-Fi driver. It's not my crappy hack but by genuine Creative :) The patch is now merged into sound-unstable GIT tree topic/ctxfi branch: git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-unstable-2.6.git The corresponding alsa-driver snapshot tarball is: ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-uns… The driver module is named as snd-ctxfi. I tested only the driver builds with recent kernels, but unfortunately I have no test hardware now, so it'd be helpful if anyone can test it with a real hardware. Note that the ctxfi driver might conflict with the HD-audio driver. So it'd be nice if you save the output of lspci before loading the drivers and let me know if any problem happens. Also, at testing, please check the kernel message. If this conflict really happens, try to build without hd-audio, that is, run configure with --with-cards=ctxfi option in addition to others, and test whether it works with this workaround (better after reboot to reset the board info by BIOS). Once after I get positive feedbacks (or fix after negative ones), I'm going to merge it to the main tree so that it'll be in the next kernel. So, a quick test report would be greatly appreciated. thanks, Takashi

[alsa-devel] Testers wanted: New SB X-Fi driver
by Daniel Bankmann 19 May '09

19 May '09

Hi! I just tested the newest driver version with Open Suse 11.1 and pae-kernel. I seems not to work probably, although the latest "official" driver by Creative worked more or less good. The problem is, that always, when hearing some music or any other sound, the signal gets interrupted every few seconds. At the other side, the startup jingle for example is accompanied by a knock every few seconds. Any idea, or what information do you need to fix this?

[alsa-devel] [PATCH] snd-hda-intel: add controls to toggle DC bias on mic ports
by Nickolas Lloyd 19 May '09

19 May '09

This patch adds a mixer control for the STAC92XX boards to control the DC bias of mic ports, allowing recording from both powered and non-powered sources. It replaces the "Mic Output Switch" with "Mic Jack Mode" to switch between Mic, Line In, and Line Out.
