Its going to take awhile, I have to get acclimated to Linux. From what I understand Linux has internal mixers too like Windows. So I want to make sure I have bypassed all the junk to get the best performance possible. This includes choosing the right player, much like how different players sound different in Windows. Since my machine is dual boot I should not have a problem comparing the two over the same system.

So far though, it sounds great with BMPx player

I guess you read my posts over here regarding Music Player Daemon and my
DIY-Audio Wiki. You can use quite some tweaks I am mentioning over there even for your Distro.

Don't waste your time with other stuff. Been there - done that.

I am personally using brutefir as the player engine. But that's
not beginner stuff.

Your output setting needs to be something like "hw:0,0" for direct hw access. Type aplay -l in a terminal. This will show your cards and outputs.
It is possible that your digital port sits on index 1 of card 0.
Than you would have to choose "hw:0,1" as output.
I'd guess that if you run digital out to e.g. hw:0,1 , your ALSA controls wouldn't work - but I am not sure. You let us know.

If your soundcard of choice is the 2nd in the system, it'll get Index 1.
Output of choice would be (hw:1,0)

If your volume control still works, you're using the soundcard
hw-mixer. Make sure all sliders are on 0db!!!!!!!! By default they
are not. Going to 100% on the HW-mixer adds usually heavy distortions, since you end up at +6db of gain or so.

Good luck.

When I type aplay -l I get this....my volume control does work so I guess I need to play around a bit to get things right.

The Intel card showed just the analog out with aplay -l as far as I've seen.

Obviously this is not the whole story.

In this case you usually have to add your model-id (codec and PC brand) to your soundcard driver module.

Run following commands and show me the output:

cat /proc/asound/card0/codec*
cat /proc/asound/card1/codec*

You could also run my ALSA upgrade script at Ubuntu forums to get the latest drivers. Since you don't have Ubuntu you gotta problem.

Follow below link and then the link in the Trouble shooting section.
You can start learn a lot about Alsa.

LOL...sure its what I wanted but I don't know how I got it.

Is it the sound.conf file that will enable me to get sound out of different cards? I'd like to be able to switch and/or if possible get a digital signal through to my coax outputs.

Settings in Sound Preferences, alsa Volume Control and Pulseaudio have no affect....and I mean none, because no matter what I have any of them set too I only get sound from card #0

run in a terminal:

alsamixer -c0
or
alsamixer -c1
or
alsamixer -c2

c0-2 equals the index of your soundcard

each card will have its own mixersetting

Check for MM (muted) on each of the sliders. Type m to toogle the mute mode.

and try following from a terminal:

replace "any.wav-file" with your .wav-file of choice.

aplay -Dhw:0,0 -fcd any.wav-file
aplay -Dhw:1,0 -fcd any.wav-file
aplay -Dhw:2,0 -fcd any.wav-file
aplay -Dplughw:0,0 -fcd any.wav-file
aplay -Dplughw:1,0 -fcd any.wav-file
aplay -Dplughw:2,0 -fcd any.wav-file

Let us know what happens.

I ran the commands for each card and made sure nothing was muted. Currently I have the C-Media card connected to my DAC...which has a lock light so I know if I am getting a signal. No light. Also does the wav file need to be in a certain dir. I have one on my desktop but I got a message that no such file or directory

RE: Odd, posted on December 5, 2008 at 07:07:01
soundchekk Audiophile Posts: 816 Location: DUS Joined: July 11, 2007	Yep. That might be correct, if you've assigned index 0 to the transit. The transit seems to work, since ALSA can see it. Did you try the analog out?

RE: Odd, posted on December 5, 2008 at 07:12:11
Dynaudio_Rules	Yes the analog on the Transit works also.... I think ALSA can see all 3 because when I type alsamixer -c0, -c1, -c2 I get a window for each of the cards. Is there a way to change the default in ALSA? like I said the GUI's have no affect so it must be a file somewhere that needs to be manipulated...[guessing] Karma Means Never Having To Say You're Sorry

Very good question (and you left out dmix and ESD). Its a little confusing.

kmix, dmix and ESD are desktop audio mixers. Their overall function is similar to Kmixer. They take the audio streams from multiple applications and combine them together, applying resampling where necessary to get a single stream at a single sample rate to the hardware. For good quality sound you want to bypass these if you can, which is almost always possible in linux.

Pulseaudio does the above and more. It has lots of different input and output hooks to try and get its hands on everything audio in your system. Its also supports sending data between two computers. This is a pretty heavy weight piece of software and probably not a great idea to be using for very high quality audio. It also is fairly new and has a lot of problems on some systems.

Its not quite as bad as windows, if the input stream is the same sample rate and bit depth as the output and the volume is set to 100% most of these will not modify the bits, but its hard to be sure. BUT you still have an extra process running processing the stream.

Alsamixer is different, it doesn't actually process the audio stream, it just sets up driver parameters, its like the control pannel applet for most soundcards. It doesn't need to run while the sound device is doing its thing, you run it to change parameters (mute, volume etc) then quit.

Jack is a virtual patchbay. Its original purpose was to allow multiple programs to send audio data between themselves without each program having to know anything about it. Each program just thinks its talking to a soundcard, but its really going to another program. Jack has been designed to be as light weight as possible, with the absolute minimum latency as possible. Jack can be setup to talk to alsa for output, input or virtual soundcard ports. It also has the capability to talk between computers.

Of the above alsamixer is the only thing maybe necessary to play audio. If you are just playing two channel audio to analog outs on the one and only sound device in a system you probably don't even have to touch alsamixer.

Alsa itself has three different levels of interface, HW, plug, and OSS emulation. HW talks directly to the hardware, this is usually the best to use for high quality audio, but not always possible. Plug adds a resample or bit depth change if needed. It only changes things if it has to. OSS is a different sound API that has been mostly superceeded by alsa, but alsa still supports it for applications that only support OSS.

When do you need to use plug? If your application is running at a different sample rate than the hardware can support or if it is using a different bit depth than supported. For example the infamous M-Audio Audiophile 2496 will not accept 16 or 24 bit data, it only supports 32 bits! This means you have to use the plug layer, which takes the 16 bit data and converts to 32. In this case the bits are exactly the same, its just repackaging them so the driver will be happy.

In order to bypass the above mixers you have to tell each application (player etc.) to use alsa as the ouput and specify the HW interface, such as HW:0,0 . For plug use hwplug:0,0

Exactly how you specify the output device is going to be a little bit different from app to app. If you leave the output device set to default you will most likely get one of the above mixers in the chain.

So you if this is the case? Thanks, Alan

Squeezeslave uses OSS by default (I think there is an alsa option in there now) so if you are using an alsa based system it is going through the OSS emulator.

Whether alsamixer has an effect on the sound depends on the driver and the hardware. Alsamixer just tells the "soundcard" to change the volume, muting etc. If the soundcard (USB DAC in your case) doesn't have a hardware volume control or software controlable mute then what you do in alsamixer will have no effect. That still does not mean it is bypassing a mixer, but since its using OSS it probably is in your case since I don't think Ubuntu installs an OSS mixer by default.

change default card in alsa, posted on December 6, 2008 at 08:11:21

bullethead

here's how to change the default card.

You might need to create a file called ".asoundrc" just the "dot"asoundrc in your /home/userx directory (where userx is your username), instructions link below.
