Unfortunately all this code has been moved about a lot in the latest code in order to share the code with the non-ASoC AC97 driver so your patch won't apply - see the topic/asoc branch of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git for the latest code.

[alsa-devel] Streams
by James Courtier-Dutton 19 Dec '08

19 Dec '08

Hi, There was some talk some time ago of maybe moving alsa to a streams approach instead of ring buffer and periods approach. Has anything become of this? Is there a plan to improve the abstraction between hardware and user space regarding constraints on period sizes when doing sample rate conversion? Kind Regards James

[alsa-devel] 44.1khz capture on CA0106?
by Takashi Iwai 19 Dec '08

19 Dec '08

Hi, can anyone confirm that 44.1kHz capture on CA0106 causes the problem with 48kHz playback? Typically, recording via 44.kHz using hw device, then run 48kHz playback. % arecord -fcd -Dhw:0 foo.wav % aplay -Dhw:0 48khz-samples.wav I got a bug report about this, and disabling 44.1kHz capture fixes the problem. His case is with MSI K8N mobo, and I'd like to know whether this happens in general on CA0106. The bug report is found in https://bugzilla.novell.com/show_bug.cgi?id=447624 thanks, Takashi

[alsa-devel] ca0106 SPDIF defaults
by Ben Stanley 19 Dec '08

19 Dec '08

Hi, I previously reported problems that are still plaguing me [1] to do with SPDIF settings that don't reset properly. I am now looking at doing a patch to the ca0106 driver to fix this problem. It appears I have to add a new control to be able to set the default settings. I presume this introduces complications with existing settings in asound.state? Is there some collected wisdom on how to add new controls while providing a migration/upgrade/interoperability path? Ben Stanley.

[alsa-devel] [PATCH] ALSA: Add support for TV-out to the jack reporting API
by Jani Nikula 18 Dec '08

18 Dec '08

Add support for reporting new jack types SND_JACK_TVOUT and SND_JACK_AVOUT (a combination of LINEOUT and TVOUT) to the jack reporting API. Also add the corresponding SW_TVOUT_INSERT switch to the input system header.

[alsa-devel] SND_SOC_DAIFMT_NB_NF meaning
by Troy Kisky 17 Dec '08

17 Dec '08

A quick question here. Does SND_SOC_DAIFMT_NB_NF have a standard meaning or does it depend on what mode your in (I2S, DSP_A, right just). From looking at the sources, SND_SOC_DAIFMT_NB_NF usually means that data is valid on the rising BCLK and start of frame is rising edge if DSP mode. The reason I ask, is that I'd like to pass the same flags to the codec and the cpu_dai and have them agree with the interpretation. Thanks Troy

But the stream* proc file should be created for snd-usb-audio when CONFIG_PROC_FS and CONFIG_SND_VERBOSE_PROCFS are set. At least, there is no change in the ALSA upstream side.
