Re: [alsa-devel] Can someone verify support for "AzTech Sound Galaxy Nova 16 Extra II-3D - using AZT-2316/R Chipset - FCC-ID:I38-MMSN846" ?

Yes, its like you said Rene, sb8 works although the sound is distorted and the module can't be removed... Later I can modprobe sgalaxy too, and the sound works without a hitch. Also since now I can compile some code - your "eeprom.c" compiles and works - I'm available for further testing... I also noticed that the binary you sent was 506kb while my compilation is 9kb, maybe you sent an early/later version with some additional includes for verbose ? I compiled it with "gcc -W -Wall -o eeprom eeprom.c" like you said (on my xubuntu 7.04 with build-essentials deb package installed). See attachment... Ram Kromberg ramkromberg(a)mail.com

You did it Rene !!! >sudo ./eeprom >sudo modprobe snd-sgalaxy sbport=0x220 wssport=0x530 It's working now !! I downloaded the binary (i didn't compile the code), chmod it, sudo it and the sgalaxy worked !!! the sb8 didn't work but I don't really care for that anyhow :-) For the record, I tested it on xubuntu 7.04 with xmms. Are you now planning to implement the code to the driver itself ? If you want me to test anything, let me know. i'm also considering installing slackware 11 since I need the preformance... THANKS !!!

[alsa-devel] Audio DMA buffer layout
by Markus Korber 16 May '07

16 May '07

Hi, I'm working with a custom sound chip with its own DMA hardware. The figure shows how the I2S DMA expects data to be prepared: IRQ1 +----------------+ | page_3 (right) |\ +----------------+ > double buffer 1 | page_2 (left) |/ IRQ0 +----------------+ | page_1 (right) |\ +----------------+ > double buffer 0 | page_0 (left) |/ +----------------+ The hardware has 2 double buffers, each containing left and right sample regions, i.e. it alternately transmits samples from page_0 and page_1, i.e. double buffer 0, then generates an interrupt and starts transmitting page_2 and page_3. After that another interrupt is generated and the process begins again with double buffer 0. So my question is, how to tell ALSA about this memory layout? Is it possible to operate in MMAP mode with SNDRV_PCM_INFO_NONINTERLEAVED? But then, how to tell the application that it should either fill double buffer 0 or 1? Or should I use RW mode and copy samples manually to another buffer? Or something else? SG-DMA? page()-callback? Best regards, Markus Korber

[alsa-devel] Steinberg Midex 8 driver development
by Norman Schleicher 16 May '07

16 May '07

I am currently on development for the Steinberg Midex8 USB driver. At the moment I can send notes to my Midi equipment via this device. Receiving is currently not implemented. My questions are: 1. Are there any tools to test the Alsa-Midi compatiblity ? 2. May I release some milestone results to the Alsa project ? Eg when the driver supports a small subset of send commands supported by midi. 3. What are the requirements to get released in an official alsa release package ? 4. Who is responsible for the version management ? Where can I read how the source code is organized in the repository and how to manage tags and branches for the development ?(I don't need an introduction how to use CVS, thats clear for me.) Regards Norman

[alsa-devel] Question to integrate a new driver
by Jean-Christian Hassler 15 May '07

15 May '07

Hello ! I wrote with a friend an ALSA driver for the emagic AUDIOWERK 2 soundcard. Now it works for the analog inputs/outputs. The project page is here : http://home.gna.org/aw2-alsa/index.html We have 2 questions to continue our work : 1- what is the way to submit our code to be integrated in the ALSA tree ? 2- We develop on two different version of the kernel (2.6.17-14 & 2.6.20) and the request_irq function prototype has changed between these two versions(the "struct pt_regs *" does no longer exists), how is this managed in ALSA ? Thank you
