ALSA Does Not Give Me the Option to Choose Direct Hardware Device Without Any Conversions
by xhivo from LinuxQuestions.org on (#4T1A3)
Hello,
I am using a class compliant USB DAC with a raspberry pi running piCore, and want to run Pianoteq with Direct Hardware output, which I can do no problem on the same hardware with a Debian installation, that's this is posted here rather then the hardware section.
After installing alsa, alsa-util and some other alsa packages available from piCore's package installer, I can access the USB DAC (Scarlett 2i2), but not the Direct Hardware option.
.asoundrc:
Code:pcm.!default {
type hw
card 0
}
ctl.!default {
type hw
card 0
}But still aplay -L gives me no hw: option but it does list all the other options (surround, defaults and such). The only one missing are direct hw without conversion and direct hw with conversion.
I also checked lsmod and all the modules needed seem to be loaded. I think I don't know how to configure ALSA properly for this setup. Why would it not show on piCore but work perfectly on debian? Unless some libraries or packages that are needed for direct hw access are not installed or configured on my system.
Best,
Xhivo
