Re: [alsa-devel] Question about your DSP topic branch

Hi Liam, I have two more questions about your DSP topic branch 7. I see in sdp4430.c, SDP4430 MODEM front-end dailink no_host_mode is set to SND_SOC_DAI_LINK_NO_HOST. What is the purpose of no_host_mode? Is it for use case that two physical devices can exchange audio data without host-processor intervention? If so, if user-space application tries to write to PCM buffer, will framework reject the buffer? 8. I see there is dmic codec(dmic.c) under sound/soc/codec which is pretty much just a dummy codec driver. I supposed the configuration of DMIC is done in other driver. Would it be better if we could have something like fixed voltage regulator? So, there is no need to duplicate the effort. Look forward to seeing your reply soon Thanks On 1/6/2011 3:39 PM, Patrick Lai wrote: > Hi Liam, > > I sync to your kernel DSP topic branch two days back in attempt to > understand the up-coming ASOC DSP design.

[alsa-devel] some questions about sound system
by loody 17 Mar '11

17 Mar '11

Dear all: I just install Ubuntu9.10 on my laptop and I try to update my sound system and recompile the utility. there are some questions I met: 1. when configure the utility it says checking panel.h presence... no checking for panel.h... no configure: error: required curses helper header not found and config.log is "conftest.c:10:42: error: CoreFoundation/CFPreferences.h: No such file or directory conftest.c: In function 'main': conftest.c:14: error: 'NULL' undeclared (first use in this function) conftest.c:14: error: (Each undeclared identifier is repor" the above error seems I miss install some package before. I google the name but I have no improvement. "conftest.c:20:28: error: ac_nonexistent.h: No such file or directory configure:7397: $? = 1" the above error seems the header located where the conftest.c doesn't expect. how could solve them all? 2. there are some configure file in share when I compile advance linux sound architecture. like alsa.conf. have anyone know where I can find the naming rule? appreciate your help, miloody

[alsa-devel] Channel swapping issue on TI OMAP3/TWL4030
by ylin＠mail.com 08 Mar '11

08 Mar '11

Hi, We are using a customized TI OMAP3 with TWL4030, similar to OMAP3EVM board. We noticed occasionally (after bring up few hours) the mic channel audio is swapped. Has anyone seen similar problem? Any suggestion where the problem might be? Thanks, Ying

If not, I recommend you to port the code to ASoC, thus it's the standard for embedded devices. If you have any questions, just post to alsa-devel ML. thanks, Takashi

[alsa-devel] hda : computer using EAPD as external amplifier controller
by Anisse Astier 06 Mar '11

06 Mar '11

Hi, I have this computer, with an integrated speaker. It's using an ALC662, see attached alsa-info output. By default, speaker doesn't work. Now, after playing a bit with hda-analyzer, I figured that output PIN 0x14 has EAPD enabled, which is the default way of doing things in auto configure mode. But disabling EAPD on this PIN makes speaker work. See second alsa-info attached. Is it necessary to write a full blown quirk just to modify this parameter? From what I've seen in patch_realtek, it seems we need to write the whole config for the device when adding a quirk: we can't rely on auto configuration and then put a small quirk on top of that. Am I right ? Regards, Anisse

[alsa-devel] [PATCH] add new Fermi 5xx codec IDs to snd-hda

Hello, It's my first patch/post here, i'm not sure if this list is the right place to suggest this patch. To follow up a previous commit on snd-hda : http://git.kernel.org/?p=linux/kernel/git/tiwai/sound-2.6.git;a=commitdiff;… I added a new entry in patch_hdmi.c to get sound working on my own 560 Ti card : --- patch_hdmi.c 2011-02-15 22:29:51.000000000 +0100 +++ patch_hdmi_GTX-560Ti.c 2011-02-27 23:52:56.984613414 +0100 @@ -1634,6 +1634,7 @@ { .id = 0x10de0012, .name = "GPU 12 HDMI/DP", .patch = patch_nvhdmi_8ch_89 }, { .id = 0x10de0013, .name = "GPU 13 HDMI/DP", .patch = patch_nvhdmi_8ch_89 }, { .id = 0x10de0014, .name = "GPU 14 HDMI/DP", .patch = patch_nvhdmi_8ch_89 }, +{ .id = 0x10de0016, .name = "GPU 16 HDMI/DP", .patch = patch_nvhdmi_8ch_89 }, { .id = 0x10de0018, .name = "GPU 18 HDMI/DP", .patch = patch_nvhdmi_8ch_89 }, { .id = 0x10de0019, .name = "GPU 19 HDMI/DP", .patch = patch_nvhdmi_8ch_89 }, { .id = 0x10de001a, .name = "GPU 1a HDMI/DP", .patch = patch_nvhdmi_8ch_89 }, @@ -1676,6 +1677,7 @@ MODULE_ALIAS("snd-hda-codec-id:10de0012"); MODULE_ALIAS("snd-hda-codec-id:10de0013"); MODULE_ALIAS("snd-hda-codec-id:10de0014"); +MODULE_ALIAS("snd-hda-codec-id:10de0016"); MODULE_ALIAS("snd-hda-codec-id:10de0018"); MODULE_ALIAS("snd-hda-codec-id:10de0019"); MODULE_ALIAS("snd-hda-codec-id:10de001a"); I think other 5xx cards need new value also.

[alsa-devel] K42Jc Notebook(ALC269) port switch between headset, headphone, mic
by Madura Anushanga 03 Mar '11

03 Mar '11

Hi, I want to switch between headphone, headset, mic input/output modes when I plug in devices. Alsamixer shows two capture channels, one is for the internal mic. I don't know how to use the other. I've tried switching some things on and off in hda-analyzer but I failed to get the functionality that I wanted. This notebook only has one audio port(TRS 3.5mm), so the selection is vital if I'm going to use an external mic. Currently the port is acting as an output only port. And something fishy goes on when I select "Analog Stereo Input" in profiles in Sound Preferences. It lets me use the external mic through the audio port but only if I push the jack half way, the input is detected and I can record it(but there's no sound output after I select this profile, its input only). I some how think that this is the "mic" mode and if I can get it to work on "headset" mode then I'd be able to use it for input and output. This is the information that I got from the script, http://www.alsa-project.org/db/?f=e70dae201e5d830874536be93090aef0454c8c1e Thank you, - Madura A.
