[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?

Hello all, I have a 2.6.18 kernel and I am using 1.0.12rc1 alsa driver. 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 ? Thanks Reetesh

[alsa-devel] Ubuntu sound problem - http://ubuntuforums.org/showthread.php?t=1073090
by jesse fillion 09 Apr '09

09 Apr '09

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(-)

[alsa-devel] Alsa driver issue with udev events
by reeteshchandran＠yahoo.com 08 Apr '09

08 Apr '09

Hello all, I am using Alsa driver 1.0.12RC1 on ARM platform. I have a volume control application using SALSA (small alsa) running. The app has the control device open (/dev/snd/controlC0). I have another application listening to udev events, something like udev monitor. The device in description is USB headset. The problem is when I unplug the device. When I unplug, I am not getting all udev remove events. I get only 3 remove events from /class/sound/mixer, /class/sound/dsp and /class/sound/audio. But I dont get the remove events for the USB device layer. As a result I am not able to detect that the device has been removed. This problem exists only if the app has the control device open. I closed the control device and I get all unplug events correctly. Has anyone else seen this problem ? Any pointers as to where to start looking ? Thanks and regards, Reetesh

[alsa-devel] 08-Apr unstable snapsot does not compile with Ubuntu kernel released this morning
by Susan Cragin 08 Apr '09

08 Apr '09

Background--Yesterday was the first alsa-driver unstable in a while. It did not compile with my kernel and I notified this list. Yesterday afternoon late there were some updates including a new (I think) alsa-tools. (It might have been alsa-utils.) After that, the 08-Apr drivers compiled. There was another Ubuntu 2.6.28-11 kernel released this morning. After downloading /installing that the 08-Apr unstable snapshot no longer compiles. (I tried both ./configure && make AND ./gitcompile) I don't know if this information is useful to you, or even if alsa-driver-unstable is supposed to compile with the 28 kernel. No need to respond.
