[alsa-devel] No sound on Dell Optiplex 380
by Dale Blount 25 Feb '10

25 Feb '10

Hello, I've been having issues with this new PC and sound since I got it last week. I'm not getting any sound out of the speakers. I've tried both rear speaker and front headphone jacks. It does "pop" when the snd-hda-intel module is loaded, though. I've tried all the model=X options listed for my Realtek chipset and made sure that everything is unmuted and non-zero volume. My alsa-info.sh report can be found here: http://www.alsa-project.org/db/?f=fa4aacb98b85d5a02e05df5e9bffa400409b0c21 Please let me know if I can help testing a possible fix or if any other information is needed. Thanks, Dale

[alsa-devel] ATMEL AC97 status
by Sedji Gaouaou 25 Feb '10

25 Feb '10

Hi, I am writing this mail to know what is the status of the atmel at91 ac97 patch? There is a question in the arm mailing list: http://lists.arm.linux.org.uk/lurker/message/20100224.190605.0a85b6de.en.ht… The point is that I have done some work on the ac97c.c driver so it will now support full duplex mode. So I would like to know if I can just resubmit a new patch with all the changes? Regards, Sedji Gaouaou

[alsa-devel] [PATCH] hda - remove unnecessary msleep on power state transitions
by Wu Fengguang 25 Feb '10

25 Feb '10

From: "Zhang, Rui" <rui.zhang(a)intel.com> This will save ~15ms boot time. The first 10ms sleep was introduced in commit d2595d86e5 for (buggy) Cxt codecs, so better to limit the sleep to the problem hardware. For the second 10ms sleep, the HDA spec says: Power State[1:0]: 00: Node Power state (D0) is fully on. 01: Node Power state (D1) allows for (does not require) the lowest possible power consuming state from which it can return to the "fully on" state (D0) within 10 ms, excepting analog pass through circuits (e.g., CD analog playback) which must remain fully on. 10: Node Power state (D2) allows for (does not require) the lowest possible power consuming state from which it can return to the "fully on" state (D0) within 10 ms. For modems, this is the "wake on ring" power state. 11: Node Power state (D3) allows for (does not require) lowest possible power consuming state under software control. Note that any low power state set by software must retain sufficient operational capability to properly respond to subsequent software Power State command. So 10ms is actually the max wait time. It should be safe to remove/reduce it and rely on the loop of 1ms-sleeps.

[alsa-devel] [PATCHv4 1/7] OMAP4: PMIC: Add support for twl6030 codec
by Olaya, Margarita 25 Feb '10

25 Feb '10

From: Misael Lopez Cruz <x0052729(a)ti.com> In order to have TWL6030 CODEC driver as a platform driver, codec data should be passed through twl_platform_data structure. For twl6030 audio codec, the following data may be passed: - audpwron_gpio: gpio line used to power-up/down the codec. A low-to-high transition powers codec up. Setting audpwron_gpio to a negative value means that codec will use manual power sequence instead of automatic sequence - naudint_irq: irq line for audio interrupt. twl6030 drives NAUDINT line to low when an interrupt (codec ready, plug insertion/removal, etc) is detected However, codec driver can operate if any or none of them are passed.

>> Anyways. I want to know how you'd do this. >> The OSS driver for example doesn't even seem to define a delay() callback, >> which strikes me as odd.How can it know about the delay? http://git.alsa-project.org/?p=alsa-plugins.git;a=blob_plain;f=doc/README-p… This plugin converts the ALSA API over OSS API. With this plugin, ALSA native apps can run on OSS drivers. The function supported by this plugin is limited. For example, you cannot use dmix together with this plugin. Don't expect too much :) Please note that this plugin require a real OSS driver , not ALSA oss kernel emulation e.g. you can use this oss plugin to use the aureal binary driver http://aureal.sourceforge.net/ [^ <http://aureal.sourceforge.net/>] on Fedore Core 1 when alsa au88x0 driver was not written
