[alsa-devel] include/mixer.h missing from doxygen
by Rolland Dudemaine 22 Aug '07

22 Aug '07

Hi, include/mixer.h seems to be missing from the doxygen input file list. Should be added to the INPUT list in doc/doxygen.cfg. Btw, I'm pretty new do ALSA, why is the Mixer interface marked legacy in a couple places ? Best Regards, --Rolland Dudemaine

[alsa-devel] unknown card info [snd-bt87x]
by Vincent Minder 22 Aug '07

22 Aug '07

Hello, After loading the snd-bt87x module on my Fedora 7 x86_64 box, here is what I found in the dmesg output: unknown card 0x878-0xbd11:0x1200, using default rate 32000 please mail id, board name, and, if it works, the correct digital_rate option to <alsa-devel(a)alsa-project.org> The card is a rather old and cheap "PINNACLE systems - Studio PCTV rave" The chip on the board is from Conexant: CONEXANT Fusion 878A (chip markings: 25878-13, E32673.1, 0023 KOREA) The card standard is PAL B/G. I think this model supports only MONO audio. It has TV-in, Audio-out (mini jack), Composite-in, S-VIDEO-in. TV playback is working all right (tested with "kdetv" and "tvtime"). I have sound as long as I use the Audio-out connector and bridge it to my motherboard's integrated audio Line-in . However, I didn't manage to use the internal audio capabities of that board. So I have no clue about the "correct digital_rate". (I must admit I am not familiar with these technologies at all.) Here is the output of "arecord -l" regarding this card: $ arecord -l **** List of CAPTURE Hardware Devices **** (...) card 2: Bt878 [Brooktree Bt878], device 0: Bt87x Digital [Bt87x Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: Bt878 [Brooktree Bt878], device 1: Bt87x Analog [Bt87x Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 I am using the stock Alsa package of Fedora 7 x86_64 (fully updated distribution): alsa-lib-1.0.14-1.fc7 I hope this report will be useful to you. Sincerely, Vincent Minder (Belgium)

[alsa-devel] problems writing pcm driver
by Trent Piepho 22 Aug '07

22 Aug '07

I'm trying to write an ALSA driver, but there are some thing I'm not clear on and it's not working as well as I'd like. Atomicity: trigger, pointer, and ack are atomic with respect to themselves. e.g., two copies of the trigger callback can't be running at the same time. That much is clear. But are they atomic with respect to each other? Can the trigger callback run at the same time as the pointer callback? How about the atomic callbacks with respect to the non-atomic ones? Can trigger run at the same time as prepare? The pointer callback: What exactly is the current hardware position? My hardware has a counter that tells me how many periods have been DMAed into the buffer. Suppose my period size is 256 frames and I'm doing audio capture. If pointer is called before any DMA transfers have completed, do I return 0? Now suppose it's called after one period of audio has been DMAed into the buffer. Do I return 255 or 256? After two periods have been received, should I return 511 or 0? Why is pointer called so many times? Here's a log of callbacks and irqs my driver is getting. I'm using the cycle counter to give them microsecond timestamps. My period is 256 frames at 48kHz, so each period is 5333 us. There are only two periods in the buffer. Time (us) | Callback or IRQ ---------------------------------------------- 0.000 trigger - start DMA 134.513 pointer - count 1, returned 0 160.254 IRQ - not calling snd_pcm_period_elapsed 5313.030 IRQ - called snd_pcm_period_elapsed 5318.808 pointer - count 2, returned 256 IRQ hander finished 5348.309 pointer - count 2, returned 256 10627.526 IRQ - called snd_pcm_period_elapsed 10633.075 pointer - count 3, returned 0 IRQ hander finished 10659.755 pointer - count 3, returned 0 15941.173 IRQ - called snd_pcm_period_elapsed 15946.601 pointer - count 4, returned 256 IRQ hander finished 15969.743 pointer - count 4, returned 256 [and so on] The pointer callback is called only 134 us after the trigger, before the first IRQ or a period of data could possibly be received. Why is this done? To get the position in the buffer to start at? I assumed the data should start at the beginning of the buffer, but is this not the case? You'll notice the first IRQ is received at only 160 us. The hardware generates an IRQ when each period _starts_, not when one ends. So the first IRQ is ignored, the second IRQ tells me the first period has finished, and so on. The hardware counter is the number of periods started; I have to subtract one to get the number of periods finished. When the IRQ handler calls snd_pcm_period_elapsed(), that calls the pointer callback. That's what I expected from what the docs said. But about 30 us after the pointer callback is called the first time, after the irq handler has exited, it's called again. What is the purpose of this? Is it ok that I return the same value as the previous time it was called?

Re: [alsa-devel] ESI MAYA44 PCI datasheet request
by Ash Willis 21 Aug '07

Hi Piotr, In general, I think this is good. Some points though... * I don't think you should demand firmware source. Asking for that might be seen as quite invasive. It might be a bonus to have, but I don't see anyone hacking on it. Their firmware works, It's a driver that we need. Does this card even use firmware? I guess... * Linking to a mirror probably isn't too smart if they think their infos are going to distributed all over the web. Sorry, that was my fault. I'm an idiot. I think the correct link should be http://www-old.alsa-project.org/alsa/ftp/datasheets/ * I would offer a fall back. I would propose that the approach you have mentioned is in their best interest however if they are unwilling to distribute the information freely, then the next best thing would be to find one developer that is able, willing and possesses the hardware. That's not ideal. I would prefer the second approach to no driver at all, as would you, I'm sure. However, I don't speak for anyone else when I say that. * I'm sure they know the ins and outs of open source but you should confirm with them the terms of this arrangement. NDAs are basically incompatible with this whole thing because, usually, releasing the source will breach the NDA. Make sure they know that the driver being produced is open source and licensed under the GNU GPL.

I would like toshow you the letter that I am going to send to the ESI company. I am asking you to accept this letter because I am going to send it on behalf of the ALSA development team. Any suggestions will be welcome. Dear Sir/Madam, In reply to the letter sent 14.07.2007: 2007/8/14, ESI UK Support <uksupport(a)esi-audio.com>: Dear Piotr ESI do not provide and have no plans for Linux drivers for our products However ESI are happy to provide /share information to an Individual developer within the Linux community That is able and capable to develope drivers and wishes to develope drivers Regards UK Support ESI Auditechnik I would like to ask you to share the information about ESI MAYA44 PCI card needed to write drivers on behalf of the ALSA development team. ALSA team needs all the information that you give your programmers to create drivers for the device. We would like to ask you for: - a full datasheet containing IO port layout, register descriptions and commands, - ESI MAYA44 PCI firmware, - EIS MAYA44 PCI firmware source code, - permission for the firmware to be distributed with ALSA, - source code for currnet windows drivers would be very helpful but isn't essential. There are many peope that are willing to write the driver for MAYA44 and because of the way Open-Source software and drivers are developed, in the interest of it's quality, it is important that the information about the card are accesable for all of the ALSA developers. We ask for your permision to place that information on the ALSA server for developers. Thanks to that any qualified person will have acces to it. Many other companies provided that kind of information to us this way before: http://ftp.mj2.org/pub/alsa/datasheets/ I am sure that adding this card to the list of the suported cards under the linux operating system will cause the number of satisfied ESI card users to increase. Thank you for your co-operation. -- Best Regards, Piotr Makowski ALSA Development Team

[alsa-devel] ESI MAYA44 PCI - ESI wants to collaborate!
by Piotrek 21 Aug '07

21 Aug '07

Referring to the lack of the official ALSA support of ESI MAYA44 PCI (in fact, the card does not work) I would like to ask I there are any plans to get this card working with ALSA? I would be thankful to be able to run my soundcard properly under Linux. There are also a lot of people that would appreciate your work and are waiting for maya44 pci drivers for linux: http://www.esiforum.com/show.asp?db=esi&t=esi1&mode=3&msg=793 I wrote a letter to the UK ESI SUPPORT asking if they were going to write drivers for their products for Linux systems as well. There is a reply: " Dear Piotr ESI do not provide and have no plans for Linux drivers for our products However ESI are happy to provide /share information to an Individual developer within the Linux community That is able and capable to develope drivers and wishes to develope drivers Regards UK Support ESI Auditechnik " It means that ESI will collaborate with developers who would like to write such driver and share the documentation. Again the question: Are there any plans to make ESI MAYA44 PCI card working with ALSA? I'm not a programmer but I will help you as much as I could. -- Best Regards, Piotr Makowski

[alsa-devel] Intel HDA / AD1986A problems
by Peter Skensved 21 Aug '07

21 Aug '07

Configuration : Lenovo 3000 N100 laptop with Intel HDA / Anlog Devices AD1986A soundcard running CentOS5.0 with 2.6.18-8.1.8.el5 kernel ( uses 1.0.12rc1 based alsa driver ). The driver works with the model=laptop-eapd option except for a few things : 1) Plugging in an external headset will not mute the internal speakers ( has to be done manually in alsa-mixer ) 2) The PC speaker ( bell ) appears to be permanently muted. 3) The external microphone input does not appear to be working no matter what I do. 4) When recording from the internal microphone the level is very, very low and almost drowns in static noise. Any easy way to fix the above ? Number 4 in particular ? I've tinkered with backporting what I thought were relevant differences between the latest patch_analog.c and the one used in the kernel I have (alsa-driver 1.0.12rc1 ) but I see no difference. Any other way to tweak or reconfigure the hardware ? Enable microphone boost ?? Looking at /proc/asound/card0/codec#0 makes me believe that the hardware has several unused or permanently disabled features. This particular laptop has a model number which differs slightly from the one listed in patch_analog.c ( 0768-6KU instead of 0768-4JU ). Not sure if is relevant. And finally a ( somewhat ) related question : Is it possible to get the sound card to work with the slmodem package to drive the built in modem ???

Re: [alsa-devel] ESI MAYA44 PCI - ESI wants to collaborate!

Hi Piotrek, Thanks for being so active in trying to improve ALSA support. I've written a couple of these drivers too but someone better than me should do this ;) especially if ESI is only willing to discuss this matter with one developer. Besides, I don't fancy paying £70 for the opportunity. The people at ESI will know what they need to provide: A full datasheet containing things like IO port layout, register descriptions and commands. Source code for current Windows drivers would be helpful but not essential. If the card needs firmware, then we'll need that too. It's also not essential that the source code for the firmware is provided but I think that's probably preferred as well. In either case, ESI will need to give permission for the firmware to be distributed for it to be well supported by ALSA. Otherwise, users will be responsible for extracting the firmware from their Windows drivers, and that's just not nice. Like I said, ESI will know will they need to provide: that is to say all the information they gave to their programmers to let them create the current drivers for this device. It is clear by the ESI response that they are willing to release the information on the provision that a good driver will be produced thereby making them look good. That is fair enough. I would suggest to ESI, however, that to truly create the maximum possibility of this happening, they could allow the datasheet to be held on the ALSA server. By doing this, the relevant information would be available to any developer who wanted to create the driver or make further improvements. You can point them to the address below if they don't think that sounds like something a sane company would do. http://ftp.mj2.org/pub/alsa/datasheets/ Anyway, good luck and my advice would be to try and get the info first and find a developer later. I don't know if ESI will do that though. There will always be people, floating around, who will code this up, but there's no guaranty that the company will always be as happy and friendly as they were to you :) Ash > ----- Original Message ----- > From: Piotrek <oponek(a)gmail.com> > To: "Adrian McMenamin" <adrianmcmenamin(a)gmail.com> > Subject: Re: [alsa-devel] ESI MAYA44 PCI - ESI wants to collaborate! > Date: Mon, 20 Aug 2007 22:53:53 +0200 > > > 2007/8/20, Adrian McMenamin <adrianmcmenamin(a)gmail.com>: > > > > On 20/08/07, Takashi Iwai <tiwai(a)suse.de> wrote: > > > At Sat, 18 Aug 2007 09:28:34 +0200, > > > Piotrek wrote: > > > > > > > > Referring to the lack of the official ALSA support of ESI MAYA44 > > PCI > > > > (in fact, the card does not work) I would like to ask I there are any > > plans > > > > to get this card working with ALSA?
