Which I/O are you referring to? The headphone output seems unplugged, and thus the outputs are only from other line-outs, as far as I see the codec info. Takashi

[alsa-devel] Latest snapshot - reliable source?
by Klaus Schulz 15 Dec '08

15 Dec '08

Hello Takashi. Can I regard your ftp link below as a kind of reliable source where to get the latest snapshot at any time? Can I also expect that it is compatible to latest official driver release? Because than I'd ask people in (worst) case of trouble to give it a try before spamming the mailing list. ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-sna… THX \Klaus

[alsa-devel] alsa 1.0.18 does not work for Intel onboard cards
by Paulo Cavalcanti 15 Dec '08

15 Dec '08

Hi, alsa driver 1.0.18 has been a nightmare for me. I had a perfectly working sound for my Intel D975XBX2 when using alsa driver 1.017. Going to 1.0.18 just muted my front sound. Well, maybe not everybody needs a front sound output, but I just stick with the 1.01.17 driver. Then, I -- Paulo Roma Cavalcanti LCG - UFRJ

[alsa-devel] Bugs on aspire one A150
by Maxim Levitsky 13 Dec '08

13 Dec '08

I have just bought an Aspire one A150, XP version, as it was the only available here, and installed ubuntu on it. Bugs I discovered so far: ** 1 - embedded controler works in polling mode, due to this: [ 0.708571] ACPI: EC: non-query interrupt received, switching to interrupt mode [ 1.224043] ACPI: EC: missing confirmations, switch off interrupt mode. Maybe this is the reason for the fact that gnome power manager freezes when I unplug the AC, and freezes often when I try to see battery status. (Note: same is seen on my acer aspire 5720) ** 2 - wireless: not to mention the fact that ath5k wasn't installed by default in ubuntu... wireless more or less works, but kernel log is full of backtraces. Was able to connect to my WPA2 access point. Sometimes wireless fails completely, especially after suspend to ram. Advanced features like monitor/injection work, but when I changed the card's mac address it stopped working. I also noticed that if I then start airodump, then wireless works with new mac. ** 3 - internal mic doesn't work. tried model=acer, model=auto. Overall it seems that alsa misprograms O/B realteck codec. I talk about this later. Have same issue on my acer 5720 ** 4 - wireless led doesn't work. ath5k devs, can you fix this? ** 5 - coretemp doesn't show cpu temperature, I have seen somewhere that atom support same thermal diode as core2 and only patch to detect it is needed. Please include such path in 2.6.28 if exists. ** 6 - both card readers are missing from lspci, is this normal? ** 7 - opengl is broken, I tried running neverball in fullscreen, but it shows wrong/corrupted textures (compiz is running, and working well thought) Now I installed 2.6.28-rc3 (actually latest -git) Sadly nothing improved. I only found few regressions: * Wireless now drops connection from my WPA2 access point after few minutes. I changed temporarily its wireless protection to WEP and open mode, and both work fine, maybe this is related to periodic key exchange WPA does? * System doesn't reboot/shutdown, just hangs. Best regards, Maxim Levitsky.

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
