[alsa-devel] [PATCH] ALSA: hda - Add position_fix=4 (COMBO) option
by Takashi Iwai 28 Feb '12

28 Feb '12

This patch adds a new position_fix option value, 4, as a combo mode to use LPIB for playbacks and POSBUF for captures. It's the way recommended by Intel hardware guys. Signed-off-by: Takashi Iwai <tiwai(a)suse.de> --- Seth, this is the patch to add the mode you mentioned. It'll be queued for 3.4 kernel. This mode isn't chosen as default yet, but if this is confirmed to work more reliably on Intel controllers, we can set these as default for them.

It's natural that the noise goes away in this state. Apart from that, I see no obvious problem in 3.2.0 output. Does the problem still happen when you disable "Auto-Mute Mode" mixer enum? % amixer -c0 set "Auto-Mute Mode" "Disabled" Also, try to pass algin_buffer_size=0 option to snd-hda-intel. I don't expect much that this will influence, but at least, it's a difference between 3.0 and 3.2.

[alsa-devel] [GIT PULL FOR v3.4] tea575x update to latest V4L2 framework requirements

Hi Mauro, This patch series updates the tea575x drivers to the latest V4L2 framework requirements, converts radio-maxiradio to tea575x as well and adds hwseek support to these drivers. All changes are V4L related, even though some of the patches touch sound drivers (but only the V4L parts of those sound drivers). Tested with SF16-FMR2, SF64-PCR, SF64-PCE2, SF256-PCP (Ondrej) and maxiradio (Hans).

[alsa-devel] [PATCH] ASoC: omap3beagle: Add dai link for McBSP2 master configuration (CLKS source)
by Peter Ujfalusi 28 Feb '12

28 Feb '12

Create new dai link so we can choose between two different modes of operation: PCM0: twl4030 master, McBSP2 slave (current configuration) PCM1: twl4030 slave, McBSP2 slave (SRG source is from CLKS pin) This will help us tracking down, and test different setups on Beagle board. Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)ti.com> --- Hello, While tracking down an issue regported by Grazvydas Ignotas regarding to the McBSP move series (Pandora setup was not working) I have noticed that we can use the Beagle board in a similar way as Pandora uses it (McBSP master, twl4030 slave, CLKS pin is connected to twl4030 256*FS clock output). With this patch we can switch between the two modes by playing on hw:0,0 or on hw:0,1. I will add the third option later where McBSP is the master, but the clock for SRG is coming from internal source.

Are there any kernel messages that are generated when plugging in the device? Check with 'dmesg'. Also, from the dump I can see that some string descriptors are really broken in this device.

[alsa-devel] [PATCH 00/38] Realtek HD-audio auto-parser
by Takashi Iwai 28 Feb '12

28 Feb '12

Hi, for 3.4 kernel, finally I got rid of all static quirks from HD-audio Realtek codec parser. This means that the all necessary quirks have been converted to alc_fixup either the pin-config overrides, the additional verbs, or the extra init functions. Since some machines have really weird pin mappings, I introduced the new mechanism in the parser to evaluate the best DAC->pin connections, which is based on the badness calculation. You won't notice on most of machines but some machines that have fewer DACs than necessary output pins will get different mappings by this change. The whole changes can be seen in sound git tree topic/hda branch, as usual. git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git Now it's merged to main branch, so the snapshot tarball contains these changes, too. The rest of the thread will contain the changes in patch_realtek.c. It's just for refernces, and I omitted the other files. For the complete changes, take a look at the git tree. thanks, Takashi
