Trust SC-5500p and Ubuntu
Today, I got myself an external USB sound card and tried to install it on my notebook running Ubuntu Studio. It's a Trust SC-5500p because that's the only affordable model my retailer had in stock. To cut a long story short: I didn't work as I hoped it would. I could get heavily distorted sound out of its front speaker output jack, but the rear as well as the center outputs remained silent. I thought the days of insufficient support for hardware on Linux were over, but: FAIL! Since I swore to myself that I wouldn't spent hours and hours an installing packages and hacking config files anymore, I returned the device, and I will start to look for another affordable solution. Suggestions anyone?

well it's a pity, even google redirects here when I was looking for answers, I guess I'll have to do everything myself..

Hey Adrien, you really should look into other options. I had better luck with other external sound devices recently, maybe I'll post some of that later.

Is very easy to get this sound card running into linux. You have to edit your asoundrc file and add these lines:
pcm.!default complex_convert
pcm_slave.sl3 { pcm "hw:0,0" channels 6 } pcm.complex_convert { type plug slave sl3 }
It will work like a charm

Yes! Works great for me! Thank you very much DjKork
adrien am :
Thanks DjKork! I had seen some version of what should be modified in asoundrc to make it work but nothing made it and I had given up :-/ I'll try you version

I've better version of asoundrc that enables software sourcemixing (play from more than one source at same time) this is the one from asound dmix site adapted for sc5500p
pcm.!default pasymed
pcm.my_card { type hw card 0 channels 6 # mmap_emulation true }
pcm.dmixed { type dmix ipc_key 1024 # ipc_key_add_uid false # let multiple users share # ipc_perm 0666 # IPC permissions for multi user sharing (octal, default 0600) slave { pcm "my_card" # rate 48000 # period_size 512 } }
pcm.dsnooped { type dsnoop ipc_key 2048 slave { pcm "my_card" # rate 48000 # period_size 128 } }
pcm.asymed { type asym playback.pcm "dmixed" capture.pcm "dsnooped" }
