Creative inspire M4500 not working properly on Ubuntu 9.04 - the Jaunty Jackalope

[Amit]

Binary package hint: gnome-audio

I use creative inspire M4500 sound card (4+1 speakers) on my M3A78-EM motherboard running on AMD phenom II 940 processor. I noticed that the audio is available only from two of the speakers and the bass. There is no sound from the other two speakers. The same works well in Windows.
O/P of some commands were as follows:
#lspci
04:07.0 Multimedia audio controller: Creative Labs [SB Live! Value] EMU10k1X
-------------------------------------------------------------------------------------------------------------
#sudo lspci -nn
04:07.0 Multimedia audio controller [0401]: Creative Labs [SB Live! Value] EMU10k1X [1102:0006]
-------------------------------------------------------------------------------------------------------------
#asoundconf list
Names of available sound cards:

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
