[alsa-devel] [PATCH RFC 0/3] Embed card device into struct snd_card
by Takashi Iwai 14 Feb '14

14 Feb '14

The third batch is a more intensive change; now struct device for card-object is embedded in snd_card struct. This makes the presence of the device object presistent, which can be later referred by other devices at the object creation time. Also, along with this change, the refcounting of the card object was changed just to use the standard device refcount. This needs to move the destructor into the device release callback. Onre more batch will follow. Takashi

[alsa-devel] [PATCH RFC 00/20] snd_device_* cleanups
by Takashi Iwai 14 Feb '14

14 Feb '14

This batch is aimed for cleanups of snd_device_*() usages. The major change is to introduce SNDRV_DEV_CARD type and use it for the card-level object instead of SNDRV_DEV_LOWLEVEL. The rest are simplification of snd_device_*() calls and management. Takashi

[alsa-devel] [RFC PATCH 00/24] Mandate to pass a device pointer at card creation
by Takashi Iwai 14 Feb '14

14 Feb '14

Hi, this is the first series of patches for a slight restructuring of device management in ALSA core codes. This batch makes the association of struct device mandatory to snd_card at the object creation time, so that the driver can refer to the device at any time even before registring the device. Basically, it rewrites snd_card_create() with the (re-)new snd_card_new() that requires the struct device pointer. The only upstream driver that had no device assignment was atmel/au1x00, and I revived the old patch to convert to platform_device for that. Takashi

[alsa-devel] Sound distorted on Intel HDA (Realtek ALC889) (Kernel 3.x)
by Vincent Thiele 14 Feb '14

14 Feb '14

Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) Mainboard is: http://www.asus.com/Motherboards/MAXIMUS_IV_GENEZ/ Only fix at the moment is changing "load-module module-udev-detect use_ucm=0" in "/etc/pulse/default.pa " to "load-module module-udev-detect tsched=0". With Kernel 3.13.2 and Ubuntu 13.10 sound without "load-module module-udev-detect tsched=0" is better but sometimes there is still some crackling noise. Hope you can fix this. Best regards

[alsa-devel] Maya44
by marcin＠saepia.net 14 Feb '14

Hi, what is the exact status for maya44 driver? I've found some files in alsa source named maya44.* but card is not recognized. There are also some patches to 1.0.17 floating in the net. I've also found some legacy information about the driver [1] and statement dated 2008 from this mailing list that the driver "cannot be merged without a proper sign-off" [2]. Is there any chance that it will be merged upstream? Is it technical or legal problem that prevents this from being done? How can I help? Thanks, Marcin [1] https://www.kernel.org/doc/readme/Documeantation-sound-alsa-README.maya44 [2] http://mailman.alsa-project.org/pipermail/alsa-devel/2008-May/007719.html

[alsa-devel] [PATCH] ASoC: dapm: Consistently use unsigned int for register values
by Lars-Peter Clausen 13 Feb '14

13 Feb '14

Commit f7d3c1709 ("ASoC: dapm: Change prototype of soc_widget_read") changed the signature of soc_widget_read() so that it, instead of return the register value as a int, takes a pointer to a unsigned int and stores the register value in that pointer. There are still a few places that pass a int type value to that function though. Change these to unsigned int. For more consistency also change the signature of soc_widget_write() to take a unsigned int instead of an int for the register value.

[alsa-devel] [PATCH] ASoC: max98090: sync regcache on entering STANDBY
by Dylan Reid 12 Feb '14

12 Feb '14

Sync regcache when entering STANDBY from OFF. ON isn't entered with OFF as the current state, so the registers were not being re-synced after suspend/resume. The 98088 and 98095 already call regcache_sync from STANDBY.
