Trust SC-5500p and Ubuntu

Posted by Matthias Gutjahr on

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..

Matthias Gutjahr on :

*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.

DjKork on :

*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 ;-)

Xeroo on :

*Yes! Works great for me! Thank you very much DjKork

adrien on :

*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 :-D (wow, more than a year later ;-)

djkork on :

*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 {

ipc_key 2048
slave {

# rate 48000
# period_size 128
}
}
