See the source code of amidi. You probably should be using the sequencer instead of the raw MIDI interface, in which case look at the source code of arecordmidi. HTH Clemens

[alsa-devel] Listing raw midi devices "The Right Way"?
by Jacob Ole Juul Kolding 18 Jun '08

18 Jun '08

Hello all I'm working on an app that used to run on Linux but then moved to OS X and gained MIDI capabilities. Now it's moving back to Linux so I need to be able to read midi events from devices. I already found a code example that reads raw midi packages form a specified device but I need to have a complete list of ALL raw midi capable devices and ports on the system. What is the "Right Way" for an app to build such a list? Sincerely Jacob Kolding Juvul Tech

[alsa-devel] hda-intel on Asus M2N-X Plus NVIDIA GeForce 6100/nForce 430 mobo
by Nigel Henry 17 Jun '08

17 Jun '08

I've just built a new machine, and expected problems with the onboard soundcard, and also have problems with the onboard NIC, but that's another problem, which is resolved by installing my last remaining realtek 8139 PCI card. Anyway the mobo is an Asus M2N-X Plus NVIDIA GeForce 6100/nForce 430, and the Southbridge (which appears to handle allsorts of stuff) is MCP61. the specs for the soundcard from the Asus site are below. ALC662 6-Channel High Definition Audio Azalia CODEC Support Jack-Sensing, Enumeration, Multi-streaming S/PDIF out on back I/O port This is using the Fedora 8 distro, which has alsa driver 1.0.15, and is probably a bit old. The card is not detected at bootup, but I did a modprobe snd-hda-intel, using various model options. the modules were loaded, but a cat /proc/asound/cards showed "no soundcards detected" I don't want to waste too much time on this onboard card, and will probably buy a cheap well supported card, just to get some sounds on this new machine. All the same I've run the alsa-info.sh script, and the link is below. http://pastebin.ca/1048647 Any comments, as always welcome. Btw: My other machines use Audigy2 soundblaster (emu10k1) on the first machine, and Ensoniq (ens1371) on the other machine, and no problems with these cards at all. I cannot repeat my opinions/thoughts about hda-intel cards. Thanks for all your work you folks. Nigel.

[alsa-devel] Thoughts on ASOC v2 driver architecture
by Jon Smirl 17 Jun '08

17 Jun '08

I'm trying to sort out an architecture that will let all of the code used in my ASOC drivers to be automatically loaded by the kernel. So if I'm confused and have some of this wrong please explain where I've gone astray. First, what are the physical hardware devices present? From the device tree it says I have two i2s controllers each with an i2c controlled codec. It also says I have a system wide DMA controller. And finally there is the "fabric" which represent the specific pcb (populated jacks, etc) used by the system (the root of the device tree). Upon booting the kernel it will find the five open firmware devices (two i2s, two codecs, one DMA) and load the appropriate of drivers for them. Note that this is the system wide DMA driver, not the ASOC one. Three drivers will be loaded and five devices will be created. The codec devices will each register one codec and multiple codec DAIs. Each i2c channel will register a platform_dai. The next part, the platform device, is where I'm having trouble. Why is the DMA subsystem in it's own ASOC device? I already have a separate system wide device for my DMA hardware. Looking at the implementations of a couple of the ASOC DMA drivers, there is nothing global about the driver, everything is done with per channel instances. Should the DMA code instead simply be a library that is linked to by the i2s drivers? And then move the entry points registered by the DMA driver up into the platform_dai? It seems to me like implementation of the DMA code should be a private matter for the platform_dai/i2s driver. Note that I'm not saying that there shouldn't be modularized ASOC DMA code, instead, why should ASOC be aware of this shared code? To see if this model would work I tried to visualize a system where one i2s controller is using DMA and the second is doing programmed IO. So if the DMA API is pushed into the platform_dai that would free up the platform device. It could then be used to support the fabric code (fabric is the motherboard specific bits of code). It should probably be renamed to the machine device instead of platform device. To handle the case of HDA not needing a fabric driver, ASOC would have a default internal machine driver that a fabric driver could override. This also implies that the fabric driver can't be the last driver registered with ASOC. There would be one global fabric driver, but it would get called on a per instance basis. You could implement (made up scenarios) two amps on the motherboard and only enough power to turn one of them on. Or maybe a front panel switch that switches which channel the front panel controls act on. I'd end up with this object model generic machine (optional machine specific fabric override) platform i2s (platform_dai, soc_snd_card) generic codec (choice of codec dai) platform i2s (platform_dai, soc_snd_card) generic codec (choice of codec dai) The platform specific i2s drivers are linked to a shared library of platform DMA code. -- Jon Smirl jonsmirl(a)gmail.com

[alsa-devel] Mute sound
by Jorge Peixoto de Morais Neto 17 Jun '08

17 Jun '08

Hi. Under kernel 2.6.23, I could get sound from the alsa device created by the module snd_bt87x. In kernel 2.6.24, there is no sound. Also, in kernel 2.6.23 the device would only appear if I modprobed the module with the option load_all=1. In kernel 2.6.24, the option load_all=1 is unnecessary for the device to appear. This is probably because I have in 2007 sent an email to this list with information about my board (it was responded by Takashi). If you need any addition other than what I provide below, ask at any time. jorge@jorge ~ $ uname -a Linux jorge 2.6.24-gentoo-r8d #4 Mon Jun 16 17:58:17 BRT 2008 i686 AMD Athlon(tm) XP 2600+ AuthenticAMD GNU/Linux jorge@jorge ~ $ sudo lspci -v 00:00.0 Host bridge: VIA Technologies, Inc.
