[alsa-devel] snd_dummy on Centos - Redhat
by Giovanni Maruzzelli 03 Sep '09

03 Sep '09

Hi all, I'm the maintainer of skypiax, a channel driver for FreeSWITCH and Asterisk that allows to connect to the Skype network (eg: http://wiki.freeswitch.org/wiki/Skypiax ). I'm trying to use snd-dummy 1.0.20 as a fake soundcard on a regular Centos installation (verified with both 5.2 and 5.3, fully updated). I tested with both the packages "stable" from ATrpms.net and compiling from the source of alsa-project.org. It gives me bad timing to the program that depends on it (eg: Skype), resulting in unacceptable behavior. On the same machine, same Centos kernel and distro, if I use 1.0.20 snd-hda-intel or snd-usb, no problem. On the same machine, snd_dummy with other distro, no problem. On the same machine, same Centos, if I compile and install a kernel, snd_dummy has no problem. So, it's a specific problem of incompatibility between snd-dummy and the kernel of Centos 5.2 and 5.3 (same kernels as in RHEL5). I'm trying hard to find where the problem is, but I'm not having success. Please please please, can someone have a look at it? If more informations are needed, I'm willing to cooperate. Thanks in advance, -giovanni

[alsa-devel] ASoC: About wm8994 codec driver
by Joonyoung Shim 03 Sep '09

03 Sep '09

Hi, Mark. I have a target including the wolfson wm8994 codec chip, so i will implement the wm8994 codec driver. I wonder if you have a plan to implement it. I don't want a duplicate work. Thank you.

[alsa-devel] <alsa-dev> RFC for OMAP4 audio driver
by hari n 03 Sep '09

03 Sep '09

Hardware Background ------------------- ABE (Audio back end) IP on the OMAP4 SoC of TI provides digital audio signal processing features (real-time mixing, equalization, etc) on the media processor. ABE allows flexible routing of the audio paths with dedicated equalizer and acoustics protection for earphone/ headphone, hands-free and vibra paths. Typically the ABE is connected to a companion analog audio chip via a dedicated McPDM (multi-channel pulse density modulation) as show at http://dev.omapzoom.org/?p=misael/kernel-audio.git;a=blob;f=sound/soc/codec… ; Proposal -------- On OMAP4, audio codec functionality is spread between ABE of OMAP4 and the companion analog audio chip. The interface between the ABE and Phoenix audio chip is proprietary McPDM interface. The proposal is to combine both ABE and Phoenix into a codec driver. OMAP4 ABE also provides other links for routing digital processed data to McBSP, McASP interfaces, which are at the same level as McPDM interface. +---------+ +---------------------+ ALSA Library --|ASOC Core|--|OMAP4 Platform Driver| +---------+ +---------------------+ | <DMA-DAI> | +-----------------------+ |ABE--<McPDM>--Phoenix--|--o Speaker/MIC +-----------------------+ ABE provides a FIFO interface (similar to McBSP FIFO) and the audio data transfer between the audio buffers and ABE FIFO is handled through the CPU DAI. Handling of the McPDM interface between the digital audio (ABE) and analog audio chip (Phoenix) is handled internally in the codec driver as part of the codec DAI operations. This RFC addresses the basic audio usecases using Phoenix companion chip with the OMAP4 audio IP block. Support and configuration for using different codecs (connectivity with BT/FM etc) using I2S/PCM interfaces are targeted for future enhancements. High Level Design ----------------- Following are the files consisting of the TI OMAP4 audio driver: sound/soc/omap/omap-pcm.c: This is the platform driver for OMAP audio. It remains the same across all OMAP chip versions. sound/soc/codecs/abe-twl6030.c: This is the codec driver interface file for OMAP4 audio. It defines the codec DAIs for the HIFI, voice and Vibra subdevices. Handles the configuration of Phoenix companion chip using i2c control interface. Handles the initialization and configuration of ABE. All codec related widget controls are also handled in this file. Both, digital (ABE) and analog (twl6030) widgets will be contained in this same driver. sound/soc/codecs/abe/*: This folder contains the ABE specific handlers. i.e reset, clock, configuration of ABE ports for different stream inputs/outputs etc. sound/soc/omap/oma-abe.c: This is the DAI driver towards the abe. sound/soc/omap/sdp4430.c: This is the machine driver for SDP4430 and defines the stream connections. Questions --------- How to handle routing of digital audio from ABE to external devices like Bluetooth/FM connectivity devices which are usually connected using McBSP interfaces?. In these scenarios, we need another DAI between the ABE (platform codec) and an external codec. ABE(platform Codec (Digital) -----> Phoenix audio codec | | +--> BT/FM codec

[alsa-devel] Alsa on HP Pavilion dv6-1225ee audio problems
by Munzir Taha (منذر طه) 02 Sep '09

02 Sep '09

Hi sirs, I bought this http://h10010.www1.hp.com/wwpc/me/en/ho/WF06b/321957-321957-3329744-64354-6… and found the audio is not working and thankfully gnubien on #alsa pointed me to manually add snd-hda-intel: model=hp-hdx which really made the sound come out of the speakers though the laptop is not hdx series. Now when I plug the headset the Speakers are still playing (no auto sensoring?) and I had to mute them manually which could be a feature or a bug depending on how you look at it. alsa-info.sh: http://www.alsa-project.org/db/?f=dcbcc7d98ffceb95cd7491aed02064fba337bfa7 I hope this would help you properly support this nice laptop out of the box. -- Munzir Taha Telecommunications and Electronics Engineer Master CIW Designer, ICDL, MOUS, Linux+, LPI, SCSA Riyadh, SA

So please mention more.... This should be addressed to the alsa developers. Distribution specific hacks are not useful in that case.
