Public bug reported:
Alsa in Ubuntu Jaunty with the stock kernel has an odd interaction issue
with ice1724 based cards that causes no recording functions including
line and mic inputs to work or show up in pulseaudio.
Examples of some ice1724-based cards:
* Terratec Aureon Space 7.1
* Terratec Aureon Sky/Fun 5.1
* M-Audio Revolution 5.1
* M-Audio Revolution 7.1
* M-Audio Audiophile 192 (Experimental Output support in HG)
* ESI Juli
* ESI MAYA44 PCI
This is a pretty common chip, and these cards have fairly high recording
quality so this is quite a big deal. A one line patch has been merged
into mainline that fixes this issue completely, this patch can be found
here:
http://git.kernel.org/?p=linux/kernel/git/tiwai/sound-2.6.git;a=commitdiff;h=bd3c200e6d5495343c91db66d2acf1853b57a141;hp=43189a38dada053b820fafc47de8ba665dd3a618
I strongly recommend that the Ubuntu kernel developers integrate this
patch with the Ubuntu kernel to get recording working on all of these
ice1724 cards.
