After disabling analog inputs, and enabled back, the inputs are still mute until reboot

[GoogleCodeExporter]

What soundcard to you have (make, model, chip)?
St-lab M170, CMI-8768

What steps will reproduce the problem?
1. disable analog input on cmi control panel so enable spdif in
2. recording works in spdif
3. disabling spdif in so enabling analog inputs??

What is the expected output? What happens instead?
If I enable analog inputs to record in analog, I can't record anything,
even if I restart the application, which i've been using, or even not from
windows sound recorder, but on next reboot everything works.

What version of the driver are you using? On what operating system? What
version of the operationg system are you using (32 or 64 bit)?

1.2.3. Windows XP 32bit

What ports of the soundcard are affected by the bug (e.g. SPDIF, Mic-In)?
none? because it's working after reboot, but I have to reboot... 

Please provide any additional information below.

Thanks

I'm using Spdif in, and analog line in, I haven't tried it with mic in so i 
don't
know if it would work...  so these ports are affected...

thank you for the report.

have you tried flipping back and forth a few switches in the control panel 
applet? If this doesn't help, I'll take a 
look at it - unfortunately, I'm a bit stuffed right now so this has to wait to 
May.

I have tried flipping some switches(checkboxes), but no help...

But: now I can't reproduce the error anymore... ? :(

I have to note that I'm using a Magic Card ( www.rogev.com ), it's like Norton 
Ghost,
it can recover an alredy saved 'state' of a PC hard drive, i only have to press 
F4
before boot, so I've checked the above reported error many times, at first I 
had only
restored the original state of my pc the state without your driver, so the 
problem
solved, then I've tried to install it again, to a 'clean' windows install the 
problem
came, and I've realised that it disappears on reboot, but not before...

but now I've tried to check some things in the control panel applet to check 
for what
you have written and I've realised that the problem is not existing right 
now... ?

Even more if I switch SPDIF input on and feed some spdif signal through the 
optical
spdif in, and feed analog signal through line in, I only have to set digital in
either analog and stop recording and begin it again
so i don't even have to restart the windows recorder...

But now as I'm writing this to you the problem appeared again...

so what?? i don't know how can i cause this....

My setup now is: winamp open playing some music, and i can record it via an 
optical
loopback cable between spdif optical in and out
and an analogue noise(white noise) generator device is on the line in

if I set the cmi control applet to enable digital in i can record it ( i can 
see from
the waveform which source it is)
and if i switch back to analog and I stop the windows sound recorder i can 
record the
analog noise...

but there is a point where winamp freezes... and then the analog input is 
mute...

but before i haven't tried this setup this way, i've been playing around with 
rmaa
audio tester, testing my new cmi sound card...

so I don't know what, sorry for the long post, I hope you have some ideas on 
this,
but no problem if you can look at it later, because I don't switch between 
inputs
this regularly during a normal use...

Thanks

This sounds familiar. I installed the driver and had a similar problem. Sorry, I
haven't investigated in detail but it seems to arise when you allow the analogue
output to link to the DAC. Then play something in vial the SPDIF input and you 
can
hear it on the speakers and record eg, in Goldwave. But then if I try and play 
back
from Goldwave, I can't get any analogue sound. Ditto no sound with the speaker 
test.

Can't remember whether I needed to reboot in the end or whether flicking 
switches
fixed it in the end. But what I've been doing now, since I only want to record, 
is
not to bother whether the DAC to analogue. I've got meters that show the 
recording
taking place. But would be nice if it was fixed eventually.

Will try and investigate further...

Otherwise, fantastic driver, Dogbert. Fixed real problems I was having 
recording with
other drivers - and I tried a few!

Thanks for your fix I'm going to try it and investigate it many ways, after 
I've done
something else I have to do on time, for school, but thanks for your work in 
advance

I can confirm your fix now! But remember, there has already occured that i 
couldn't
reproduce the error, but now it seems to be working, here is what i've done:

1. I've plugged in a mic, in mic-in, and headphones in line out
2. I've started windows sound recorder
3. I've recorded my voice, and played it back, i could hear myself
4. I've gone to your control panel, then set Digital in on(so off analouge in)
5. I've tried to record using the same sound recorder, the recording didn't 
even start
6. I've ticked out the Digital input option(so analouge is on)
7. I could continue recording
8. I could hear my voice, when played back (I've recorded something different 
than
the first, so I could distinguish between the old recording, and then the 'new' 
one
after the analouge in has been switched back

Thank you

WAIT!
I've got the issue again, it or something like that occurs when i'm using the 
digital
in too. i'm testing it with RMAA6 (a free software, Right Mark audio Analyzer, 
if you
don't know it, it can produce some sounds thus it can measure the audio 
performance
of a sound card, though it 'measured' my other cmedia card as the worst of all 
my 3
cards, it still sounds the best, has the clearest sound, but it is good for 
using the
optical in and out on the card, because i don't have any digital source here 
now, and
when i've first discovered this issue, i had also been using rmaa, so maybe the 
error
is inconnection with it, i'm testing now and i'm going to write what i'll've 
found in
a few minutes

It seems like i've got it finally:
and found a cure for it, but it needs some work from you :) but it doesn't need 
the
reboot
Here is what i've done:

1. I have the card with analogue input switched on
2. Open the RMAA6 application
3. With having the '[MME]CMI8738/8768 Wave' device selected, as recording and
playback device too, I open the loopback test window
4. while the test calibration signal is being played(i can hear it on my 
headphones),
and see that the recording is from my microphone, i can see much more sound 
(ambient
noise probably) than with digital loopback recording
5. switch on the digital input (the card's output is connected to the input via 
a
TOSLINK cable), and i can see the sound spectrum much clearer, 'no' noise 
except for
the calibration signal at 1Khz
6. !Disable the digital input while this calibration signal is on!
7. the test shows that it can still record through the digital in
8. close RMAA
9. open Windows sound recorder (according to the control panel the analogue 
input is
on (at least digital is off))
10. try to record sound, no sound is recorded
11. try to switch digital back, then Apply, then analogue back, then Apply
12. try to record, still no sound

i could only get the analogue input back if i:
13. tick the digital input checkbox back
14. TRY TO RECORD from windows sound recorder (I haven't tried any other app, 
but i
think sound recorder would do, or maybe this is causing the problem, tell me if 
i
sould try it with some other program too)
15. then stop recording, and switch back to analogue input on the CMI Control 
Panel
16. THEN RECORDING WORKS AGAIN :)

thanks for reading this novel

Well spotted. I'll shortly release a new version that eradicates this bug - 
please 
confirm the fix.

Thank you! It's great! It's working, I can switch on and off the digital in, 
even
when feeding the test signal in RMAA, as I switch on the control panel, it is
switching the signal from analogue to digital and vice versa! So I even didn't 
have
to restart any application including the windows sound recorder, which i've also
tried. I've had some interesting issues with Audacity before, that it couldn't 
find
any device or something like that, it's like one other mentioned issue in the 
list,
i'm going to investigate it too.

Excellent - thanks again for the detailed report and the testing! I'm happy 
about any bug I can swat.
