[PlanetCCRMA] Tascam 428

[Eric Princen]

OK. I think we are slowly getting somewhere...

I rebooted to have it at normal startup. No audio plays. I don't have
speakers connected to the onboard audio, so it may be playing there
since the 428 isn't yet recognized.

I added usbmidi and audio to /etc/hostplug/blacklist

root@studio ~]# cat /etc/modprobe.conf

alias sound-service-0-1 snd-seq-oss

Should I remove the oss stuff?

Yup. I thought it was loaded because the USB light is lit on the unit.
Perhaps I got lucky. I haven't cycled power on the unit itself. Perhaps
that wasn't the best test... :-)

I tried using XMMS with the ALSA plugin. It sees the 428 by this time,
but I can't get anything to play.

Even thought hotplug blacklists usbmidi, I still get those messages on
an alsasound restart. On a hotplug, /var/log/messages gives me:

us428control is not running after the hotplug.

If I unplug the 428's usb and power, then power it up, then plug in the
USB, the firmware is not loaded. It takes a manual usx2yloader to have
that happen.
