[alsa-devel] [PATCH2/2] hda: Add support for IDT codecs to report jack presence

[alsa-devel] hda: broken PCM over spdif after AC3; suggestion
by Tomas Cernaj 21 Oct '08

21 Oct '08

Hello, trying to track down a long standing bug concerning PCM output over spdif and analog ports simultaneously after AC3 passthrough (see https://bugs.launchpad.net/bugs/25632 ), I've been digging into the inner workings of HD Audio... It seems to me that after playing DVDs with AC3 passthrough the stream associated with the default alsa device is only connected to the front Audio Output widget but not at the same time to the Digital output widget, as I would have expected. I've attached the contents of /proc/asound/Intel/codec#0 during music playback to this mail; you can see the different streams connected to nodes 0x02 and 0x03. I'm not familiar with the hda driver, but I suspect that after AC3 passthrough the multi-out configuration isn't reset to what it's supposed to be. Is there a way to work around this issue, or am I completely missing the point? Thanks for your help, Tomas

Re: [alsa-devel] Microphone array using ALSA

Ola Benderious had written: > Would it be possible to use several USB soundcards in GNU/Linux using > ALSA to build a microphone array? I have searched the Internet but > haven't found any straight answers. What I have read is that it might be > hard to sync the captured streams even if it would be possible. > > So, three questions. > 1. Is it theoretically possible? > 2. Can it be done using several USB soundcards? > 3. Do you know of any code or project in this area as it is? A friend of mine (Pete Mander) from England recently sent me the following information on ambisonic mics. I wrote: > On another front, I'm planning on using my GadgetLabs cards to work with Helmut Oellers creating a WaveFieldSynthesis system using 32 PC style speakers in my house (they have the amps built in). Since the GL cards would only need to be outputs, I believe it may be possible to get 4 of them to work in a linux system (however, that's to be tested). http://www.syntheticwave.de Pete replied: I did ponder whether I could do ambisonic recordings with the GL. The rigorously synchronised channels are perfect for this. I'll need to find time and a child safe workshop to build the soundfield mic from condenser capsules and the circuits: http://www.ambisonia.com/wiki/index.php/Microphones#Home_made_tetrahedrons Later on, Pete provided these additional fruits from his research: http://parts.digikey.co.uk/1/1/27254-microphone-cartridge-9-7mm-x-5mm-wm-55a 103.html http://homepage.ntlworld.com/henry01/cheap_soundfield/cheap_soundfield.htm http://www.kokkinizita.net/linuxaudio/tetra-pict.html http://en.wikipedia.org/wiki/Head-related_transfer_function If you want to be cc'd on the correspondence between Pete, Helmut, and me, send me a note off-line. To answer your questions: Q. Is it possible? A. Yes, but it doesn't quite make much sense to me unless there is some way to play back what the mics record. Q. Can it be done with several USB soundcards? A. The simple answer is no. My opinion is that you'd want to sync the samples so they would not drift apart. I don't know of an easy way to do this unless the soundcards are sync'd Q. Do you know of any code or project in this area as it is? No, I don't know of one. In addition, it will be a month or two before we even have a way to play back sources from multiple locations. We are trying to play a few 'tricks' by positioning the speakers in a room so that 32 channels sound like there are much more than 32 channels. If you are going to play games with an array of mics in order to find the position of a sound source, it seems that using multiple ambisonic mics is the way to go. Regards, Mike Mazarick (PS - if you had a slightly bigger budget, it would be quite possible to do the same type of thing and set up a WFS system with the RME 96/52 cards)

OK, then it must be a regression. If it works with Linus tree, the problem is the post 2.6.28 stuff. If it doesn't work with Linus tree, too, it's likely changes to patch_realtek.c... thanks, Takashi

[alsa-devel] [PATCH] pci: use pci_ioremap_bar() in sound/
by Arjan van de Ven 21 Oct '08

21 Oct '08

From 6666b6edd4a0c496932ef1640b742cc72f9c57d8 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven <arjan(a)linux.intel.com> Date: Sun, 28 Sep 2008 16:20:09 -0700 Subject: [PATCH] pci: use pci_ioremap_bar() in sound/ Use the newly introduced pci_ioremap_bar() function in sound/. pci_ioremap_bar() just takes a pci device and a bar number, with the goal of making it really hard to get wrong, while also having a central place to stick sanity checks.
