[alsa-devel] Notebook Toshiba satellite x200-21g with realtek snd-hda-intel audio device still not supported (codec ALC268)
by Daniele (Mastro) 19 Feb '08

hi all i'm new to this mailing list i've bought a laptop and i would like to help you supporting my sound card what works: 2 speaker, low volume (it should be a 5+1 audio card) what doesn't -) low volume -) inoperating headphone jack -) not working mic -) no subwoofer -) may be some other stuff not tested ( SPDIF? hardware midi?) with speaker-test -t wav -c 6 only front left/right channel works my kernel is a debian kernel Linux Luffy 2.6.23-1-686-bigmem #1 SMP Wed Dec 5 02:42:05 UTC 2007 i686 GNU/Linux alsa 1.0.15 drivers (compiled with debian-way: module-assistant a-i alsa-source) i've already tried all the option i could think about auto (default) toshiba 3stacks 3stacks-6ch 3stacks-6ch-dig neither one has better/worst behavior I've checked the module has toke those option by cat /sys/module/snd_hda_intel/parameters/model anyway I've read the ALSA-Configuration.txt shipped with kernel and for Codec ALC268 it only has 4 options ALC268 3stack 3-stack model toshiba Toshiba A205 acer Acer laptops auto auto-config reading BIOS (default) I've googled a bit and i found out that the Toshiba A205 has completely different problem.. the sound doesn't work with it.. reading the changelog from 1.0.14 to 1.0.15 (alsa) it say: Added the proper model=toshiba for Toshiba A305 with ALC268 codec. so i think my audio card is an unknown model the laptop is brand new and i only found this model in Italy anyway i think that the same audio card is shipped with the Toshiba Satellite x205-S7483 witch is an american laptop some info about the audio card: lspci -n 00:1b.0 0403:

be glad to help you if you ask.. i don't mind compiling some other driver/kernel/tool for this just ask me one last note: searching the internet i've found this page: https://wiki.ubuntu.com/Gutsy_Intel_HD_Audio_Controller if you go down you find that the Toshiba Satellite x205-S7483 has the exact same problem here. I think they have the same card searching the Realtek web site i didn't find any 6 channel audio card with the ALC268 codec may be this mean the ALC268 is not the right codec for my audio card or this is a really new model/heavily Toshiba modified device i've already filed a bug https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3659 please ask me if you need any more info or want me to do some test thanks you all for your work ps: i've subscribed to vger mailing list, what's the right mailing list for alsa-devel? -- Daniele Segato

[alsa-devel] Maya44 revised patch
by Rainer Zimmermann 19 Feb '08

19 Feb '08

This is the revised version of the ESI Maya44 patch. changes are mainly coding style, some cleanups and using a patch file for ice1724.c . The added code now (mostly) passes checkpatch.pl, except for some "#if 0"'s which I'd leave in for the development phase. Also, I changed the rate setting logic, which (for now) allows all rates up to 192kHz even for capturing. As capturing actually only supports 96 kHz, while capturing & playback rates are linked, this is not really ok. I'd appreciate suggestions about how this could be handled properly, while still supporting playback up to 192 kHz... Again, feedback & testing is appreciated. For more information, see doc/README.maya44 . -Rainer -- Lightshed IT Services Löfflerstr. 27, 22765 Hamburg, Germany * mail(a)lightshed.de * www.lightshed.de

[alsa-devel] snd-hda-intel AD1981 - Sound volume low level
by Robert Gonciarz 19 Feb '08

19 Feb '08

Hi, I just want to ask you if you have heard about the problem with low sound volume level even though you set the alsamixer on the (almost) maximum volume level. The sound card: snd-hda-intel / AD1981 / ICH7 ) It's a big problem for me especially when I watch a movie with ac3 (DVD quality) decoded sound. The volume level is extrimly low in such situation (I mean the level you hear the sound). I have to connect my loudspeakers to a ampilifier and set it in very high level. I don't have such problem when I work with Windows XP. They are loud enough. That's alsa-info.sh result: http://pastebin.ca/908831 It is said that there are some preferences in the totem package (hidden in alsamixer) that can fix it and make alsa to remember higher sound level. I've noticed that problem with all kernels I tested (I've checked about 15-20 kernels from that range 2.6.13.x - 2.6.24.x) (I usually use vanillia kernel (from www.kernel.org) /with build alsa/). But I've tested the newest alsa-drivers: 1.0.16 with 2.6.24.2 kernel also and the result was the same. Could you chack that problem, please? Robert

Re: [alsa-devel] Problem with setting period time and buffer time.
by Ignacy Kasperowicz 19 Feb '08

19 Feb '08

Ok, so I misunderstood the idea of a period variable, many thanks for explanation Clemens. I've just read that buffer_time also isn't what I think it was ;) It's a size of the ring buffer of sound card and it's length depends on hardware, am I right? So the best way is to depend on default values of hardware? Anyway is there a method to play my wave for a specified short time? As I can see using timer interface is the only solution but still can't google anything useful :( Small example how to apply timers will be appreciated (I saw example timer.c from alsa-lib, but I'd prefer to read some explanation how the code works). Thanks from advance for any replays. -- ################################################ gry świetlicowe drogą do wyższej fazy przemian. gg:681548 jid: fik(a)jabbim.pl usecide.net ################################################

[alsa-devel] Problem with setting period time and buffer time.
by Ignacy Kasperowicz 19 Feb '08

19 Feb '08

Hello. I need to set proper period time for my application. What I need my code to do is to play sine wave with set frequency and for exact time of 1/1200 s (something about 834 us). When I try to set period time for 834 us I've got this error: Unable to set period time 834 for playback: Invalid argument . Honestly speaking I've got this error message no matter what value I try to set). The same situation take place when I try to set buffer time for something about 1000us (so one period could fit in my buffer). The purpose of this program is to generate sine wave for AFSK (audio frequency-shift keying). I want to play wave for period_time (834us) then if needed change frequency and play changed wave again for period_time with phase shifting. Wave generation with phase shifting for variable frequencies works, but not with period_time I need. Could anyone look at source and tell me why I can't set this values? I placed code with syntax highlighting at: http://pygments.org/demo/606/ . (Don't look at prepare_message function, it isn't used right now). Thanks from advice. Ignacy. -- ################################################ gry świetlicowe drogą do wyższej fazy przemian. gg:681548 jid: fik(a)jabbim.pl usecide.net ################################################

[alsa-devel] Cirrus Logic CS42L52 Low power codec
by Brian Austin 18 Feb '08

18 Feb '08

Hello, I have a codec I would like to submit. The Cirrus Logic CS42L52 Low Power codec. I have the codec code as well as the machine code for the Cirrus Logic EP9407A, but cannot submit that yet. Is it OK to just submit the codec code for now? This does not use the new API, so a hint as to which tree to make the diff from would help. Thanks, Brian Austin

[alsa-devel] Problem with DELL XPS M1530
by Travis Place 18 Feb '08

18 Feb '08

Hi all, Been helping a user on #alsa for a day or two now, with issues regarding recording from Mic on his Dell XPS M1530 laptop. He originally had alsa-driver 1.0.14, so i had him upgrade to 1.0.16. Now, his Mic works for recording, but he has lost playback on one of his HP jacks (the right one), and Internal laptop speakers. I had a brief look at the code in patch_sigmatel.c, to see what was going on.. But since im no code guru, i wasnt much help.. The output of alsa-info.sh is located at http://pastebin.ca/908579 I did notice some comments in the code about correcting HP and Mic jacks for certain models (atleast thats what I read it as). Any ideas would be appreciated. Travis (wishie). -- Happiness is like peeing your pants. Everyone can see it, but only you can feel its warmth
