That is, something like the following? Thanks I'll add Mark to the discussion here, for the ASoC point of view. Mark, the original mail is in [1]. I originaly thought we would change pxa_set_ac97_info(), to add a parameter which will be the platform data for the gpio. IOW, have something like : void __init pxa_set_ac97_info(struct pxa2xx_ac97_platform_data *pdata) { pxa_register_device(&pxa_device_ac97, ops); } The trouble is, I saw references to the platform data as pxa2xx_audio_ops_t*, mostly to suspend and resume a card. I've seen them in pxa2xx_ac97_do_suspend(), pxa2xx_ac97_do_resume(). Mark, could you please have a glance at it, and tell us the right approach to have the struct pxa2xx_ac97_platform_data passed to pxa2xx-ac97 please ?

Thanks a lot Lee.

I am facing some issues and would like to get a newer alsa driver. I cant change the linux kernel version. Do you know which is the latest alsa driver which is supported on linux 2.6.18 ? How do I find that out ? The latest should work. New ALSA releases are backwards compatible with old kernels. Lee

[alsa-devel] DELL SP2309W Monitor with Integrated microphone
by Phil Gorbett 11 Apr '09

11 Apr '09

Any luck anyone with this one yet? I too have the same issue as that posted previously (last month), and get the same results with the indicative testing. I have tried several fixes via googling - module loading and sound "card" indexing via alsa.base modprobe file and LOTS of others. Still no luck. I am running FC10 with pulse, but think it's probably a snd-usb-audio problem as the driver appears to be correctly loading and the webcam is clearly indicated in the sound prefs app and gconf/gstreamer. I have run thru the usb audio device classes, and all of the reported class values reported via lsusb -v seem to correctly correspond to possible values from the audio class parameters. I'm now stumped. I do get the following errors in the gnome sound recorder: "Could not negotiate format" followed by "Could not get/set settings from/on resource.". This jives with the error from the sound preference panel: "gconfaudiosrc ! audioconvert ! audioresample ! gconfaudiosink profile=chat: Could not get/set settings from/on resource." which does not reveal anything specific enough to track down the problem from searching the net. All other sound devices and services are performing correctly via pulseaudio. I have at one time removed p/a, but this did not correct the problem. I am running the webcam mic as device 0, but changing that to any other device number fails to solve the problem. Alsamixer shows the card "Monitor Webcam" mic, the chip "USB mixer", the recording levels at 74, the capture enabled, and the AGC and loudness parameters enabled, and although I have tried various combinations of these, none have worked. I am running version 1.0.19 of the alsa drivers, and compiled these directly with all everything enabled as well as using the rpm builds. Alsainfo has been uploaded to: http://www.alsa-project.org/db/?f=803829378929c58bcc86351c091719a12c79075e The video portion of the camera functions entirely correctly via uvc and v4l, but the audio listing from the video test app gucveiw does not list the webcam mic at all under the audio device list. The uvc dev group sent me here, naturally. Cheers, PG

[alsa-devel] oss emul: powerbook5,3 microphone to mono
by Robert T. Drury 11 Apr '09

11 Apr '09

On machine powerbook5,3 the built-in microphone is attached to the right channel of the sound chip. In the alsa oss emulation in linux-2.6.23.9 (alsa-*-1.0.12) the plugin layer copies the left input channel to a one-channel buffer when calling ioctl SNDCTL_DSP_CHANNELS with one channel. So no mic to mono on the powerbook5,3. In the kernel source: linux-2.6.23.9/sound/core/oss/pcm_plugin.c: The function snd_pcm_plug_read_transfer copies from the two channel hardware input buffer to the one channel user space buffer. The left source channel appears to be selected for copy in function snd_pcm_plug_format_plugins. One approach is to query line/mic input there for powerbook5,3 and select right channel source for copy. Any ideas?

[alsa-devel] Ubuntu sound problem - http://ubuntuforums.org/showthread.php?t=1073090

Good afternoon, My name is Jesse. Forgive me if this is not the correct address to be sending this type of request to, but I am looking for support in getting the Alsa drivers to work correctly with HP DV4 laptops. The DV4 1228ca has a Azalia RS780 soundcard. I have the ability to hear music through the headphone jack, but not the internal speakers (please see ubuntu forum for additional information). I would truly appreciate any information you could provide. Thank you. -Jesse Hi, I'm relatively new to Ubuntu and would be thrilled for any assistance anyone can provide me with this problem. I have an HP DV4 1228ca. Just like everyone, I did have sound through my front audio jack and could listen to with headphones. Unfortunately after trying all of your helpful suggestions, I don't even have audio in my front jack anymore. If I go into my sound properties, it doesnt seem to recognize my sound card anymore. I beleive this has to do with the entry in the alsa base file.

[alsa-devel] [PATCH 0/3] ASoC: omap-mcbsp, osk5912 and tlv320aic23 DSP mode change
by Peter Ujfalusi 09 Apr '09

09 Apr '09

Hello, While I was trying to implement the four channel mode for the twl4030 codec, I have noticed, that the DSP_B mode implementation in omap-mcbsp and tlv320aic23 is not coorect, also for me it seams that the osk5912 configuration for the DSP mode is incorrect (based on the tlv320aic32 datasheet). The following series tries to correct this by: - Adding DSP_A support for the codec (setting the LRP bit for the DSP mode) - Changing the DSP_B mode to DSP_A mode in omap-mcbsp - Correcting the dai format configuration for the osk5912 board file. Please note, that I don't have access to osk5912 board, but based on the available documentation, I think the changes in this series are correct. --- Peter Ujfalusi (3): ASoC: tlv320aic32: add DSP_A format support ASoC: omap-mcbsp: change the DSP_B mode to DSP_A mode ASoC: osk5912: Use the correct DSP_A mode sound/soc/codecs/tlv320aic23.c | 2 ++ sound/soc/omap/omap-mcbsp.c | 4 ++-- sound/soc/omap/osk5912.c | 8 ++++---- 3 files changed, 8 insertions(+), 6 deletions(-)
