[alsa-devel] Unregister and register the sound card
by Bharath Ramachandramurthy 26 Jul '12

26 Jul '12

Hi After the kernel has booted up and sound card detection is also fine, if there is a requirement To unregister the sound card and re-register it back to ALSA SOC framework, what is the recommendation, Especially when platform, codec & cpu dai drivers are registering with ALSA framework only at bootime ? Am noticing that when sound card is unregistered(platform_device_unregister), all dai links gets deregistered (pls note the driver is not removed from kernel, only the device is removed from alsa framework) but when I try to add the same using platform_device_add(soc-audio), observe that dai links registration doesn't go thru fine as the cpu dais are not re-registered back to ALSA framework. This is because the probes of the cpu dais weren't called as it was not never unregistered with the kernel. What is the best way to overcome this pbm ? Thanks Bharath

[alsa-devel] [PATCH] ASoC: jack: Always update jack state even for noop changes
by Mark Brown 26 Jul '12

26 Jul '12

Now that DAPM is very cheap for most updates we've no need to avoid trying to run it so always notify even if we don't think there are any changes. This avoids potential issues with bootstrapping state like the pin state or other notifiers when there's nothing in the jack.

[alsa-devel] ALSA concurrent use case for 5.1 LPCM on HDMI.
by gsantosh＠codeaurora.org 26 Jul '12

26 Jul '12

Hi All, I have following use case I am facing an issue with the ALSA framework, Consider a use case 1) System tone or any stream running on Front End 0 with stereo channel configuration On Back End 0(HDMI) 2) Start a local file playback for 5.1 LPCM on Front End 1 with 5.1 channel configuration On Back End 0(HDMI) Here FE0 and FE1 is routed to same BE0. When step 2 is done I see following behavior of ALSA which is not correct. Framework will check that the BE0 is running with FE0 routed and running, Framework will not trigger the fixup and hw_params callback to re configure the session for FE1 with 5.1 channel. With this effect we are playing the FE1 session with stereo instead of 5.1 channel configuration, how to rectify this issue? Regards, Santosh M G.

[alsa-devel] [PATCH] ia64: rename platform_name to ia64_platform_name
by Fengguang Wu 25 Jul '12

25 Jul '12

The macro name is too generic and conflicts with snd_soc_dai_link.platform_name, which triggers lots of ALSA build errors.

[alsa-devel] kernel v3.4.x wrong pins / hp z400
by Florian Reitmeir 25 Jul '12

25 Jul '12

Hi, i own an HP Z400 Workstation, and audio is not working as expected. The Problem: - if i mute the internal speaker, the sound for line out is also muted - pulse audio, detects the internal speaker as master, so if if use the volume control in gnome 3, line-out gets muted, and the internal speaker is used - to hear something on line-out i use alsamixer, and control the volume of the "speaker" output to 0 - but even if i set the output of speaker to 0, i can hear the music very very silent.. - and last .. the control of "line" does nothing, mute/volume does not affect the output Here some hardware info, if you need more, please tell me. Thanks. greetings > uname -a Linux schrank 3.4.3 #1 SMP PREEMPT Wed Jun 20 01:15:11 CEST 2012 x86_64 GNU/Linux > lspci -v 00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio
