[Alsa-devel] AudioScience driver
Hello all, thanks to various people on this list, I have managed to make an ALSA driver that works for most AudioScience cards. I have attached a patch against alsa-driver-0.9.4 But I'm not sure if this is the desired form, or whether I have located the driver in the correct part of the tree. This driver depends on a module external to ALSA (asihpi, (GPL), available from our website). I couldn't figure out how to add a driver specific include path, so I made a symbolic link across to the (only one) header file. Any constructive advice on how to proceed will be appreciated, thanks and regards Eliot Blennerhassett AudioScience Inc. -- Junk footer beyond this point.

It may be the fact that the application in question is using the RTC, and the clock just doesn't align with that tempo. Wild guess. (MIDI apps or JACK usually run it at 1024 ticks/second, so figure how that would align with 163.7 ticks/s.) I haven't had any latency problems with the unit or the driver itself.

Yes, but I tested Alsa (a long time ago) with both MIDI-IN driving soft synths, and then MIDI-IN/MIDI-OUT driving hardware synths and got the same 'note stuck on' problem. For that reason I say it's a 'MIDI-IN dropped note' problem, but certainly I do not know this for sure. > > dropping a note is surely a bug of the driver. > unless the FIFO overflows, no dropping should happen. > > btw, could you try the attached patch? > (and in-advance-scheduled excuse if it causes a hang-up :) > I would be happy to try a bit of patching. However, I am on Redhat/PlanetCCRMA and Gentoo, both of which provide prebuilt Alsa environments. I can try patching the Gentoo one which is pretty recent, but it may take a few days before I can get back to you. --- This SF.Net email is sponsored by: INetU Attention Web Developers & Consultants: Become An INetU Hosting Partner.

[Alsa-devel] New mixer api.
Hi, If a user has a 5.1 sound card, but only has 2 speakers connected, it would be nice if the user could tell alsa this fact. Then the amount of sliders in the mixer could be reduced, and also, an application could detect what the user has set up. It would be nice for the user to only have to tell one application(maybe the mixer app) that they only have 2 speakers connected to a 5.1 sound card, and then all other applications run by the user would automatically pick up that information. It seems to me, that the best place to store this infomation is in alsa somewhere. It would also be nicer to have a better description language for the mixer elements, so that a single GUI mixer, could draw a diagram of how each mixer element effects which other ones. This idea could probably be expanded for some sound cards, whereby the mixer GUI could be used to let the user design their own mixer setup. E.g. The SB Live could be programmed for all sorts of different mixing setups. So, as a suggestion, each mixer element should have extra meta info like this: - Entry: 1 Type: output Description: Front Speakers. Entry: 2 Type: Mixer Description: Volume Range: 1-100 Channels: Left and Right Input comes from (3) Output goes to (1). Entry: 3 Type: input Description: PCM stream from computer. One could have multiple "Input comes from" and "output goes to" for each mixer element. With this sort of information, a GUI could draw a nice diagram of the mixer. --- This SF.Net email is sponsored by: INetU Attention Web Developers & Consultants: Become An INetU Hosting Partner.

and plays in order the packets received from the client.
2. sychonisation issue.
3. How to over come the buffer xrun in case of playback?

I want multiple dsp channels > and 24-bit audio I/O under Linux please NVIDIA! I'm almost positive that the Soundstorm is only a 16bit/48khz part. I'm also pretty sure that nvidia never advertised the soundstorm as such. The soundstorm is generally attached to a Realtek ALC-650 for A/D-D/A functions. From the Realtek specs (http://www.realtek.com.tw/products/products1-2.aspx?modelid=30) it has a 20bit DAC but only >90dB S/N. Looking at the nvidia specs (http://www.nvidia.com/docs/lo/2027/SUPP/APU_TechBrief_71502.pdf), it looks like one might be able to do 24bit, but it looks like you'll only get 48khz. Still, because they don't really mention it, I doubt you'll get anything more than 16/48 .. later, Steve --- This SF.Net email is sponsored by: INetU Attention Web Developers & Consultants: Become An INetU Hosting Partner.

[Alsa-devel] latency with mtpav
Hi (sorry for the crossposting but I'm not sure where this one should go) In trying to test various applications with sync I have observed some serious latency problems with the mtpav driver. Using ardour I found some serious latency when starting a recording (about half a beat at 163.7 BPM (sorry the calculations escape me trying to work out the exact latency here)) Has any9one else experienced this or can come up with a resolution for this.. (No xruns were observed by wither MusE or JACK while doing this test) cheers -- Allan Klinbail <[EMAIL PROTECTED]> --- This SF.Net email is sponsored by: INetU Attention Web Developers & Consultants: Become An INetU Hosting Partner.

[Alsa-devel] intel 8x0 MIDI
Hi All In trying to test MMC response on various software I have discovered my SiS 645 DX, doesn't seem to see MIDI. The manual for the motherboard says it should, and the modules.conf configuration does show that the intel8x0 midi port does exist, (specifically MusE recognises it as MIDI port, also teste with ardour for MMC response) However this device does not see any MIDI input, including MMC. Has anyone had this successfully working either with a SiS 645DX motherboard, or simply a soundcard with this chip? Alternatively, is there something wrong with my configuration?

I think that the ordinary mixer API and simple mixer API does not have much common parts for complicated hardware. The ordinary mixer API is very highlevel and tied up to specified playback / capture streams, but the simple mixer API is still only a translation between universal controls and mixer applications.

If you use any part of it (e.g. header files) then the driver must be GPL too. You can workaround this, but it's extra work to do. There are some closed-source drivers for Linux and for X. Reading the notes of their website, I suppose they provide the sources of generic code to drive the card. Perhaps if you only use the documentation and you rewrite the driver fron scratch, you can workaround (part of) the NDA. You should ask them directly, I'm just guessing.

Re: [Alsa-devel] Lynx Studio LynxTwo/L22 Driver
Here's a question Does Alsa drivers *have* to be in source code form? Can someone not release an object file for linking They could even make a $ or two out of that if this were possible DS.

[Alsa-devel] NV Soundstorm support? / Recording broke!
Hello ALSA devs! My biggest question is- what is going on with Linux support for NVIDIA's NFORCE 2/ Soundstorm chipset? Have NVIDIA been contributing code or patches to ALSA or has the ALSA driver been created independently? More importantly, how long before we see PROPER support for the soundstorm under ALSA, instead of just a hacked intel8x0 driver? I want multiple dsp channels and 24-bit audio I/O under Linux please NVIDIA! I've been thinking of starting a petition as I'm sick of waiting for this. They release new Linux drivers for their GFX cards every other week so why can't (at least temporarily) devote some of their Linux workforce into getting Soundstorm support under ALSA sorted? The main reason for my building impatience is as Mr. PBD said that he's have that long, long, LONG awaited Ardour rc out by now- what happened Paul? We expect release candidates to have bugs- as long as it compiles under the major distros that'll be enough. Bring forth that glorious tarball pleeze!
