[alsa-devel] ACER Aspier 5630 (snd-hda-intel ALC883)
by Marcin Floryan 30 Jan '08

30 Jan '08

Hello! I have had some problems using alsa sound on openSuse 10.3 wit the above hardware: sound output OK but mic not working. Have seen many relevant bugs and with the new driver the microphone is now working OK so thanks for all the effort. I was wondering now if there is anything I could do to help with driver development to fine-tune for this particular hardware setup. I can provide some further details or do some tests if guided a bit (I am fairly comfortable modifying source code and compiling the driver) Kind regards, -- Marcin Floryan http://marcin.floryan.pl/ Please consider the environment before printing this email.

[alsa-devel] alsa-firmware licensing
by Tim Jackson 30 Jan '08

30 Jan '08

As part of the Fedora Project [1], I'm trying to package [2] the ALSA firmware up for easy distribution to Fedora users. The trouble is that the licensing seems unclear. Specifically: a) Several firmwares claim to be under the GPL but don't specify a version and don't include source - see https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3411 b) More worryingly, the Emagic EMI 2|6 firmware appears to be under a "license" which prohibits ANY redistribution. Quoting from emi_26_62/license.txt (my emphasis): "The firmware contained herein is Copyright (c) 1999-2002 Emagic as an unpublished work. This notice does not imply unrestricted or public access to this firmware which is a trade secret of Emagic, and which ***may not be reproduced, used, sold or transferred to any third party without Emagic's written consent.***" Does the ALSA project have special authorisation ("written consent") to distribute this? Who within the ALSA project is responsible for the -firmware package and might be able to help resolve some of these queries? Does anyone have a contact at Emagic (which seems to have been bought by Apple) to discuss relaxing the firmware conditions slightly? Any information most welcome. We'd really like to get the firmware in Fedora. Thanks, Tim [1] http://www.fedoraproject.org/ [2] https://bugzilla.redhat.com/show_bug.cgi?id=217259

[alsa-devel] Gateway Model: MT3707 driver??
by Ya Bra 30 Jan '08

30 Jan '08

Dear Alsa Driver's Developers, I would like to express my gratitude to you all for your hard work developing the sound driver for linux users' computers. I am a beginner Ubuntu linux user. I recently tried to install the sound driver for my Gateway Laptop. It shows in the driver list as HDA Intel with an ATI manufacture. Please let me know if your project has extended to support for sound in such laptop's vendor like Gateway. Or if you have any solution on how to configure such sound card like to work, please let me know as well. I would like to thank you in advance for your help. Yours Sincerely, Nymo Lim,

Howdy Takashi, Code: http://audioscience.com/internet/download/beta/alsa_driver3507_asihpi30909.… Firmware: http://audioscience.com/internet/download/beta/dspbins30909.tar.bz2 here is an update to the asihpi driver, please apply to alsa Hg if you see fit. (BTW the previous version was only meant to be commented on, not committed!) Main changes in this set: * Redo comment formatting so block comments are properly indented with code (bulk of changes) hpifunc.c: * Remove HPI_UNUSED macro from hpifunc * Remove error->string translation, hence strcpy hpios_linux_kernel.* * Remove use of slab cache for DMA memory allocation tracking hpicmn.*: * Rename some functions to give Hpi prefix, made others static hpimod.c * Replace semaphore with mutex * Make driver cleanup more 'normal' hpi6205.c hpi6000.c hpimsgx.c * Pull some error handling up into hpimsgx.c Relevant DSP code changes (for alsa-firmware) add record format check for supported format. ASI6500/6500 - fix issue arising from back-to-back- adapter sample rate changes. ASI6000 - fix rare MP3 decode bug. ASI6585 - add support for clock source Livewire. ASI6416 - re-order control creation. Signed-off-by: Eliot Blennerhassett <eblennerhassett(a)audioscience.com> regards -- Eliot Blennerhassett www.audioscience.com

[alsa-devel] ASOC v2 driver structure
by Jon Smirl 29 Jan '08

29 Jan '08

I'm trying to write an asoc v2 driver for my powerpc based SOC (mpc5200) hardware. We have two audio devices on the board, a WM8580 and a TAS5504. How do you do this with asoc v2? The card is created in snd_soc_machine_create(); there seems to be an assumption of a single card per machine. Or are you supposed to mix the different devices into a single pcm driver? What would happen in pxa2xx-pcm.c if more than one of these were defined? static int pxa2xx_pcm_probe(struct device *dev) { struct snd_soc_platform *platform = to_snd_soc_platform(dev); int ret; platform->pcm_ops = &pxa2xx_pcm_ops; platform->pcm_new = pxa2xx_pcm_new, platform->pcm_free = pxa2xx_pcm_free_dma_buffers, #if defined(CONFIG_SND_PXA2XX_SOC_I2S) ret = snd_soc_platform_add_dai(platform, &pxa2xx_i2s, 1); if (ret < 0) return ret; #endif #if defined(CONFIG_SND_PXA2XX_SOC_AC97) ret = snd_soc_platform_add_dai(platform, pxa2xx_ac97, 3); if (ret < 0) return ret; #endif #if defined(CONFIG_SND_PXA2XX_SOC_SSP) ret = snd_soc_platform_add_dai(platform, pxa2xx_ssp, 3); if (ret < 0) return ret; #endif ret = snd_soc_register_platform(platform); return ret; } -- Jon Smirl jonsmirl(a)gmail.com
