[LAU] karmic gnome delta 1010lt audio

hi, i'm new to this list. please pardon me if this isn't the place to ask questions like this :-) i have a delta 1010lt sound card and used to have it running nicely via envy24 with ubuntu 8.04 i recently upgraded my machine to karmic (9.10) and am having problems. i've seen various posts - some saying that pulse audio is the problem (well the implementation in karmic) and to remove it - others say pulse is ok. so i'm wondering if anyone has experience with this card on karmic and can share what works best. here's what i know .... 1. cat /proc/asound/modules gives 0 snd_ice1712 1 snd_via82xx i believe that 0 is my delta card , 1 is the built in audio on my motherboard. 2. aplay -l **** List of PLAYBACK Hardware Devices **** card 0: M1010LT [M Audio Delta 1010LT], device 0: ICE1712 multi [ICE1712 multi] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: V8237 [VIA 8237], device 0: VIA 8237 [VIA 8237] Subdevices: 4/4 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 Subdevice #3: subdevice #3 card 1: V8237 [VIA 8237], device 1: VIA 8237 [VIA 8237] Subdevices: 1/1 Subdevice #0: subdevice #0 so again - the card is showing up. 3. System->Preferences->Sound then going to the hardware tab, only shows the internal audio on my motherboard - not the 1010LT Any advice very much appreciated! -p
