[Alsa-user] Alsa compilation - lasound
Hello, I have successfully ported the alsa library to the arm platform. But I don't know what are the binaries of alsa, and where they are located. I have compiled alsa because I need to cross compile a program that depends on alsa, it is a softphone. The compilation of this program make reference to -lasound, and fails because it can't find it. I assumed that I would have as output of the compilation of alsa a few files, with lasound among then. Can anyone please help me? Please let me know if you need more information.

[Alsa-user] MCP67 audio and alsa 1.0.15
I just got a new HP laptop. Nvidia based. It has MCP67 components from lspci. I installed alsa 1.0.15 and it does not find any sound cards. I have install alsa a number of times so I am not new to that. I thought there was supposed to be support for MCP67 in 1.0.15? Any ideas? Jerry - Check out the new SourceForge.net Marketplace.

It's very likely that in your case, Toslink means optical as opposed to the usual electrical coaxial SPDIF connector. The data at both connectors will be exactly the same.

But I don't know what are the binaries of alsa, and where they are located. make install installs the binaries and the configuration files to the default location (/usr/lib and /usr/share/alsa). If you have cross- compiled alsa-lib, you usually use make DESTDIR=/somewhere to put the files below the root of the target machine's file system.

[Alsa-user] Intel ICH8 82801H (rev3) support
Hi,
I have a laptop with
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio
Controller (rev 03)
00:1b.0 0403: 8086:284b (rev 03)
I'm running ubuntu hardy with the latest ubuntu kernel (2.6.24-3) and
this card was supposed to work with it, but what I get is
hda_codec: Unknown model for ALC268, trying auto-probe from BIOS...
in dmesg. I have the mixer, but no audio output whatsoever, and seems
that this autoprobe doesn't work right :) I went and looked in different
solutions in google, and found some, but what it boiled down to was that
at patch_realtek.c, there's
/* ALC268 models */
enum {
ALC268_3ST,
ALC268_TOSHIBA,
ALC268_ACER,
ALC268_AUTO,
ALC268_MODEL_LAST /* last tag */
};
and that message shows up when the model I get is not matched in the
list, and what else I've seen online I see that the people use the
revision 2 of the hardware, and this is revision 3. It's the same in the
kernel and in the mercurial repository, so from here on - what can I do
to try to make it work?

[Alsa-user] Software volume mixer for S/PDIF output
Hello list, I have recently switched to a 5.1 Dolby Digital system and was surprised how nicely everything worked with ALSA. There is however one problem which I have - read through a lot of forums, but did not find a satisfying answer. I'm using my soundcards (Terratec Aureon 5.1 = C-Media Electronics Inc CM8738) optical output to interface my amplifier. The optical output logically always uses maximum output so no data is lost. This makes perfect sense to me. However, it is sometimes inconvenient. When my phone rings and I want to answer I'd like to make music almost completely silent by just some mouseclicks - not standing up and turning the volume down in the amplifier (no, it does not have a remote...). Some programs (like XMMS) support it, but I would like to have a more general solution which works with all programs in a unified way. So my question is: does ALSA support software volume control? The loss of quality (dynamics) is not so important to me in this case, I'd have it almost always on 100% - but would sometimes like to quickly reduce the volume. If it is supported, does it also work when playing back direct AC3 streams? If it can be done: how so?

Re: [Alsa-user] ALSA support for toslink
Can ALSA send audio to the analog ports AND the optical/toslink port at the same time? (Or is this a function of the motherboard)?

Re: [Alsa-user] ALSA support for toslink
Can ALSA send audio to the analog ports AND the optical/toslink port at the same time? (Or is this a function of the motherboard)? AFAIK most sound cards (especially onboard ones) only have one output stream. This same audio signal is sent to the analogue jacks, the coax SPDIF and the optical SPDIF. The hard part would be getting *different* audio coming out of each connection - that would require a more advanced sound card. Cheers, Adam. - Check out the new SourceForge.net Marketplace.

If it is supported, does it also work when playing back direct AC3 streams? If it can be done: how so? Yes, there is a softvol plugin you can attach to an ALSA device that will create a new mixer control. Anything played through though that device will be adjusted according to the softvol mixer control. I would've thought your card would already have a hardware mixer that supports turning the volume down though, but perhaps not. I imagine you would also need a program like xbindkeys that can run a command when a key is pressed, for example so you can press the mute button on your keyboard to run amixer and get it to set the volume to a low level. It won't work when playing AC3 streams, as the decoding is done inside the amplifier - but presumably whatever program is playing the AC3 stream has a pause button ;-) Cheers, Adam. - Check out the new SourceForge.net Marketplace.

Re: [Alsa-user] plug refuses to play audio at normal sample rates
Well, as far as I know LADSPA - it's very difficult, if not impossible, to not detect sample rate correctly. Did you look into the plugin source ? I've had a look through it, but I can't see where the code is that does sample rate conversion. Can it be that ALSA calls the plugin initialization routine with wrong sample rate ? Can it be that ALSA calls the plugin initialization routine only once and not on each sample rate change ? Since it works properly with unusual sampling rates (like 60kHz) I don't think it's an ALSA issue. It only fails when using a sampling rate directly supported by the underlying hardware - in that case it still needs to do resampling, but for whatever reason the audio is *not* resampled and playback fails. At some point there is a sample rate check, and instead of checking what sample rates the next *plugin* in the chain supports, the code incorrectly checks what sampling rates the *hardware* supports. The hardware supports four different sample rates, the plugin only supports one - so sometimes the audio isn't being resampled when it should be.
