Hello,
<br/>First: thank you for great job developing Voyage MPD - works awesome!
<br/>I upgrade to last build of Voyage MPD and on every reboot I got
<br/>different configuration for my USB DAC - sometimes is USB 1, sometimes
<br/>is USB 2 mode.
<br/>When is in USB 2 mode everything is OK, works well.
<br/>In USB 1 mode I got error message that can't open sound device and
<br/>can't play music.
<br/>Currently installed build of Voyage MPD is
<br/>voyage-mpd/voyage-mpd-0.9-rc1.tar.bz2 on ALIX3D2 board with USB DAC
<br/>M2Tech HiFace Two and without Wi-Fi card Installed.
<br/>I'm using like music source my home NAS and mount the music directory
<br/>via NFS in fstab.
<br/><br/>Is it possible to optimize the boot process and to define which module
<br/>or driver to load?
<br/><br/>Here is the result from aplay -l when everything works fine:

<br/> M2Tech M2Tech USB Audio 2.0 at
<br/>usb-0000:00:0f.5-2, high speed
<br/><br/>In "bad" configuration after reboot the info is "M2Tech USB Audio 1".
<br/>I did not found any relation between how and how often I restart the
<br/>system - just sometimes it detects USB DAC in usb 1, other time like
<br/>usb 2 device.
<br/><br/>I did not found also such issue in internet.
<br/><br/>Please, do you have any ideas how to fix this issue?
<br/>Is it possible to define manually what and how to load to avoid
<br/>detecting new sound card after reboot?
<br/><br/>Best regards,
<br/><br/>Stoyan
