Re: After warm boot Alsa not detecting sound card

[Mark Knecht <markknecht@comcast.net>]

Fernando,
   Thanks for the response. I have blacklisted the usb-midi and audio
drivers and they no longer load. as expected. 

   I discovered this afternoon that I have too much stuff in
modules.conf I think. (Actually in /etc/modules.d/alsa) 


# OSS/Free portion - card #1 (HDSP9652)
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

# OSS/Free portion - card #2 (MidiSport 2x2)
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-1 snd-seq-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-8 snd-seq-oss
alias sound-service-1-12 snd-pcm-oss


alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss


Shouldn't I remove some of the services for card #2? (The MidiSport) The
PlanetCCRMA Nano Config guide doesn't seem to show which of these 5
aliases should be used. (If any!) Can you help? I'll try removing the
mixer and pcm-oss ones, and I'll try keeping the seq-oss ones, however
all of that is just OSS support, correct? Running Alsa apps, do I care
at all about OSS support for the MidiSport? I'm thinking no, and that
maybe all 5 lines can be removed?

I will take a close look at that script on my Planet box soon and see if
I can scope out what you did. Thanks for the pointer.

With best regards,
Mark
