Hi
I have installed Voyage MPD on an old FICpc. It runs well apart from a
very annoying problem:-
The FICpc has an internal CS5535 sound chip, which CANNOT be disabled in the
BIOS
I am using a Music Streamer II+ DAC, and require MPD to connect to the
DAC.
On boot, the FICpc randomly changes the order and numbering of the devices
thus:-
root@voyage:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Audio [CS5535 Audio], device 0: CS5535 Audio [CS5535 Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: II [Music Streamer II+], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
OR
root@voyage:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: II [Music Streamer II+], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Audio [CS5535 Audio], device 0: CS5535 Audio [CS5535 Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
This of course screws up the MPD conf:-
audio_output {
type "alsa"
name "My ALSA Device"
device "plughw:0,0" # optional
# format "44100:16:2" # optional
# mixer_device "default" # optional
# mixer_control "PCM" # optional
This problem is known and there are lots of suggested ways to fix it in the
ALSA wikis, using alsa-base.conf or asound.conf to control the card numbers.
Unfortunately none of the suggested fixes work, the card numbers still
randomly switch. (I have a feeling that V3.0 kernel takes different
parameters to those suggested in the wikis)
I finally found a post from someone who appears to have had the sane issues,
and he has a very, very, complicated method of fixing using udev rules.
My question is :- Has anyone a simple way of locking the assigned card
numbers at boot, on creating a mpf.conf file that will select the usb dac
whatever its card number?
Your help will be much appreciated.
regards
Patrick
