Comment 119 for bug 178442

I had this problem with the M-Audio Audiophile 24/96. Neither analogue inputs nor outputs were showing up in PulseAudio. What fixed it for me was the patch attached to PulseAudio ticket #624:

http://www.pulseaudio.org/attachment/ticket/624/pulseaudio-add-profile-sets-for-M_Audio-Audiophile-2496.patch

Following the lead of muttnik in comment #52 above, the two files I had to edit were:

/lib/udev/rules.d/90-pulseaudio.rules
/usr/share/pulseaudio/alsa-mixer/profile-sets/m_audio-audiophile-2496.conf

I tried muttnik's customized versions of the patch first, but it did not allow applications to record from my card. The original version from ticket #624 worked, however.

Thanks to muttnik for putting me on the right track.
