Hi, Indeed gpio #3 controls the led. I patched ath5k to use it, and led works now fine. What I dislike is the way led blinks: While nether I like constant rate blinking implemented in windows driver, I don't like the fact that led blinks too fast, sometimes the blink time is so short that led doesn't show full brightness. I think there should be a minimal interval for blinking. Also I don't know what is assumed better, when led is always on, but turns off when active of vise versa? (Due to short intervals, when I set it for first option, it is almost always on, and I almost don't see the interval when it is off) Best regards, Maxim Levitsky

[alsa-devel] EMU releases 0404/0202 MAC driver stack as open source!!
by Klaus Schulz 12 Dec '08

12 Dec '08

Hi folks. FYI - see below. Does this makes live easier to get the ALSA driver developed. THX Klaus ---Quote--- SCOTTS VALLEY, CA - December 1, 2008 - E-MU Systems today announced that for the first time it will release as open source the Macintosh driver stack for its award winning USB 2.0 audio interface products - the 0202USB, 0404USB, and TrackerPre. The Software Developer Kit will be available on the SourceForge developer's website in early December and can be found at: https://sourceforge.net/projects/zaudiodrivermac/. The software will be released under the GNU Lesser General Public License or LGPL v3, which enables developers to commercially redistribute products derived from this code base. The Software Developer Kit will include the E-MU USB 2.0 driver interface specification and necessary source code for adding new features, enhancing performance, or porting to other Operating Systems. "We are releasing this code to the public to enable programming enthusiasts the ability to experiment with and to extend the capabilities of our products, which we find being used in a variety of applications outside of the MI space proper. I'm convinced that our clever user base will come up with innovative variations not addressed by our mainstream activities," said Michael Lee, marketing manager for E-MU Systems. "I'm excited to see the results generated by the OpenSource community." ---End Quote---

[alsa-devel] [Question] Can I open a substream in kernel space without attach to a file pointer?
by Bryan Wu 12 Dec '08

12 Dec '08

Hi Takashi, I am developing a USB gadget driver compliant to USB Audio Class Spec 2.0. So I want to open a PCM substream and do some playback of capture, then close them? I found snd_pcm_open_substream() is for opening a substream and attach it to a file. But in my application, there is no need to open a file before opening a substream. - Is there any interface for me to open a substream in kernel space without attach to a file? - How to playback and capture in kernel space, use snd_pcm_lib_write and snd_pcm_lib_read? - How to get the snd_pcm_hardware struct from low level driver, because I have to get the hardware configuration of the snd pcm device? And I am reading the code of OSS emulator in ALSA. It provides some info about the kernel space sound card programming. Thanks a lot -Bryan

[alsa-devel] More notes on HD-audio driver
by Takashi Iwai 11 Dec '08

11 Dec '08

Hi, per popular demand, I wrote a brief document more about HD-audio driver. It's now found in sound git tree as Documentation/sound/alsa/HD-Audio.txt. The git tree is: git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git You can get the text from web: http://git.kernel.org/?p=linux/kernel/git/tiwai/sound-2.6.git;a=blob_plain;… A PDF file is found at: http://ftp.kernel.org/pub/linux/kernel/people/tiwai/docs/HD-Audio.pdf Comments, corrections and additions are appreciated. thanks, Takashi

[alsa-devel] ASoC: asound.conf
by naveen krishna ch 11 Dec '08

11 Dec '08

Hi all, I have a custom built ASoC CODEC driver for twl4030. I am integrating my kernel (ASoC driver) with the application. The application expects a /etc/asound.conf file is there any utility to build or restore the asound.conf for my ASoC driver. I have checked the "alsactl" which can give me the state/controls information. Do i need to make a asound.conf file.If so, can any one help my with some information (a sample asound.conf) with details of the driver in it. Sorry, if this the wrong place to raise this issue. -- Thanks, (: Naveen Krishna Ch :)
