Personally, i wouldn't send back your card. The M-audio hardware has stable
and reliable drivers (modules) in linux, and there's plenty of users who
have much success with them, me included. (Mine's a Delta 44, but the
Ice1712 module is still the same)
The fact you're getting a signal in Envy24 is a good sign. So follow the
signal. Up to Envy24, you have success, as the meters show. Daniel quite
rightly suggested you check your ADCs and DACs. Do so, and put them up to a
reasonable level. Next, if you're getting a signal in the digital mixer
strip, that's good too, it means the signal is getting that far.
In the patchbay/router tab of Envy 24, make sure you have ticked:
PCM Out 1, PCM Out 2, etc..
And in the Analog Volume tab, lift the levels to something reasonable that
won't be too soft to hear, or conversly, frighten the neighbours. 90 would
probably do here to begin with.
Try your sound again.
If successful, excellent.
If not, read on......
So to a test app. Audacity is't a good choice.
If you're on UBStudio (and i assume this from the list heading), then i
suggest you download through synpatic, a simple synth to test with. When i
first started figuring out how to use Linux Audio, i used an app call
Hexter. It's a simple DX7 emulator, and possesses single audio out and midi
in, and importantly, gives you an immediate response, be it success or
temporary failure, because it's a synth, and doesn't require extra sound
libraries or soundfonts.
So how do you hook your midi keyboard into Hexter?
At kernel level, you'll find Alsa, and your ice1712 module is inserted
But a level above that is the mighty Jack, a powerful 'Hub' that enables you
have several apps, or 'clients' working together at the same time. Jack
intereacts with Alsa using a 'backend', which is the software sound device
of your choice, be it Alsa, oss, Ffado, Freebob, or dummy.
So the next step is to install, from Synaptic, Jackd, and Qjackctl. This
will give you not only the Jack Hub, or Server, as it's called, but a user
interface in the form of Qjackctl (Also known as Jack Control).
Once you've done this, open Qjackctl, and go to setup.
In the setup window, you'll find some settings on the right, starting from
near the top, which is the driver selection. As you've already had success
with an Alsa/Envy signal response, choose Alsa.
Next, you'll see a drop down box marked Interface. You can leave this as
default for now, provided you selected Alsa as the sound weapon of choice.
Then go down to Audio. Here you 'll see three dropdown options, Duplex,
Capture, and Playback. For now, leave this on duplex.
Next, you'll see input device, and output device, These are, by default, set
on, erm, default. With the arrow to the right of each box check the device.
Mine has Delta 44 as hw:0, and Ice1712 as hw:0.0. If this is the case with
you, then leave these as default, for now.
Now go to the middle of the setup window, and find Frames/Period (leave the
priority selection alone for now.)
We'll try a relaxed setting first of 1024.
Then sample rate. Check in the Envy24 hardware settings tab, for which
sample rate you have ticked. (Mine is 44100, but many users run with 48000,
so if you hav either of these, it's ok)
Back to the Qjackctl setup window.
Set the samplerate to that which matches your Envy hardware setting. (In my
case it's 44100)
Next, Periods/Buffer. Set this to a safe "3".
Next settings are Port Maximum, and Timeout. You can leave the Port Max as
is, but change the Timeout to 2000, as this will give your system some
'slack' to work with.
Then go to Start Delay, and make this 2secs, if it isn't already.
Lastly, go to the bottom left corner of the setup window, and choose a midi
driver. To have a place to start, choose Seq.
Ok, if you got this far, then save the settings, close the setup window, and
hit start in the normal Qjackctl window.
Don't panic if it doesn't start straight away. If you get a popup message
window, with some error details, please post them here, and we'll take it
p.s. Setting up audio/midi in linux in general isn't as difficult as it
looks. It's just different, and requires a little thought and patience on
the part of the user.
And we've all been where you are now. :)
