== APPLICATION VERSION ==
Mixxx 1.10.0 beta 1

== OPERATING SYSTEM ==
Lubuntu 11.10

== CPU ==
Intel Core Duo T2500 2.0GHz

== VIDEO ==
$ lspci | grep -i vga
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility X1400

== AUDIO ==
The culprit of this crime is a Samson Go Mic USB microphone:
http://www.samsontech.com/samson/products/microphones/usb-microphones/gomic/
The microphone has an headphone output, so the fact that it's listed in output is no surprise. Obviously, however, it should have an input. Even lsusb agrees its primary function is that of a microphone :D
$ lsusb | grep -i samson
Bus 002 Device 003: ID 17a0:0302 Samson Technologies Corp. GoMic compact condenser microphone

ALSA sees it as a playback device:
$ aplay -l

ALSA sees it as a capture device, too:
$ arecord --list-devices
**** List of CAPTURE Hardware Devices ****

card 2: GoMic [Samson GoMic], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

By the way, I use the iMic for headphones. Yes, it also has an 1/8" microphone jack. Haven't had good luck (audio quality-wise, for a good price) with such devices, thus the USB solution. NEVERMIND THE iMIC in other words. Sorry for the confusion ;)

== REPRODUCTION ==
Simple stuff here:
1. Plug in mic.
2. Load Mixxx.
3. Open Options > Sound Hardware > Input > Microphone
4. Go Mic does not appear.
5. Open Options > Sound Hardware > Output and pick any of the options (e.g. Master)
6. Go Mic does appear.
7. Select Go Mic for output.
8. Open Options > Sound Hardware > Input > Microphone
9. Go Mic still does not appear.
10. Requery devices and nothing changes.
11. Try different sample rates, apply, and requery devices and nothing changes.
12. To be sure it is not a bug in PortAudio, use the mic in Audacity with no problems, so the problem does not lie there.

== IN CONCLUSION ==
Thank you, Mixxx Development Team, to finally implementing the talkover feature. I have been waiting desperately for it. Can't wait to put it to good use with my microphone!

Same situation with iMac running OS X 10.6.8 on a 3.06 GHz Intel Core i3 (built in audio) and an ATI Radeon HD 4670. Obviously using Core Audio.

Hey wxl23,

I noticed you commented in Bug #⁠887917 about the iMic working with input and output enabled. Does that mean this problem is fixed?

Oops -- nevermind. I just saw this report is not about the iMic.

Could it be that the microphone is being presented as a stereo ALSA device? Bill, don't we explicitly filter for mono devices for the mic input?

Well mixxxdj/mixxx#4910 the iMac ain't using ALSA ;)
mixxxdj/mixxx#4911 it seems to be mono if i understand alsamixer correctly (see attached) as for it to be stereo that "47" would be "47<>47" or something similar.

Hey Walter,

Does your system have pulseaudio installed? How are you running Mixxx, from the desktop icon or from the terminal?

Could you try running it like this:

$ pasuspender mixxx

I'm wondering if Pulseaudio is somehow locking your GoMic capture device. This doesn't make sense since you said it works in Audacity, but just to rule it out, could you please give it a try? :)

Would you mind compiling, running and pasting the output of http://portaudio.com/trac/browser/portaudio/trunk/examples/pa_devs.c (direct link to c file: http://portaudio.com/trac/export/1796/portaudio/trunk/examples/pa_devs.c)?

It should compile with gcc -lportaudio -o pa_devs pa_devs.c; you may need to install portaudio19-dev first.

It'll list all the devices portaudio is seeing and give various info about them, hopefully it'll give a hint as to why Mixxx isn't displaying your microphone. I know you mentioned Audacity doesn't have any issues with it, but I think Audacity bundles its own copy of portaudio in its packages so it's possible there's some difference (also, knowing the info we're getting from PortAudio will likely be useful to know).

I've tried running graphically and in the terminal to no avail.
pasuspender offered no help.

Hey Walter,

Did you install portaudio19-dev? If you have, then could you try opening
pa_devs.c and changing:

#include "portaudio.h"

to

#include <portaudio.h>

And give it another try?

Would you mind compiling, running and pasting the output of

It should compile with gcc -lportaudio -o pa_devs pa_devs.c; you may
need to install portaudio19-dev first.

It'll list all the devices portaudio is seeing and give various info
about them, hopefully it'll give a hint as to why Mixxx isn't displaying
your microphone. I know you mentioned Audacity doesn't have any issues
with it, but I think Audacity bundles its own copy of portaudio in its
packages so it's possible there's some difference (also, knowing the
info we're getting from PortAudio will likely be useful to know).

Issue also affects Windows 7. It seems that Mixxx does not yet support USB microphones.

The file is moved and is now at https://subversion.assembla.com/svn/portaudio/portaudio/trunk/examples/pa_devs.c

Can you try this:

gcc -I/usr/include/ -pthread -lportaudio -lasound -lm -lpthread -o pa_devs pa_devs.c

also, double checking that 
#include "portaudio.h" 
is turned into
#include <portaudio.h>

Bill -- I see this line in SoundManager in setupDevices:

if (device->getNumInputChannels() <= 1) //Ignore mono input and no-input devices

This means we're ignoring all mono devices? wxl and Chris -- do you know if your USB mics are mono or stereo?

and by #⁠7 above it's mono. so perhaps that's the source of the problem. is that filter necessary?

wxl23 confirms this is a mono microphone.

When you get the chance to build from source, could you try this change:

open mixxx/src/soundmanager.cpp and on line 186 from:

if (device->getNumInputChannels() <= 1)

to:

if (device->getNumInputChannels() <= 0)

first things first (this is partially a reminder to myself):
wiki suggests libusb-dev, but libusb-1.0-0-dev is needed

also when doing a universal install:
Install file: "Mixxx-Manual.pdf" as
"/usr/share/doc/mixxx/Mixxx-Manual.pdf"
scons: *** [/usr/share/doc/mixxx/Mixxx-Manual.pdf]
/usr/share/doc/mixxx/Mixxx-Manual.pdf: No such file or directory
scons: building terminated because of errors.
but it seems build was successful as can run from menu or command line
anywhere and it works fine.

now for the punchline:
it worked. :)

Thanks everyone for the help and patience, I stared at my preferences code forever looking for this but never thought to look to see if we were filtering devices in SoundManager.
