eric wrotei would like to remove retrovol too

This isn't about retrovol

eric wrote but it's difficult to fing a good replacement

retrovol is fine. leave it. retrovol doesn't depend on asoundconf

Update: although if you are using alsaconf just to automate the correct sound card for retrovol, alsa-tray can handle both. (therefore no need for alsaconf or retrovol just alsa-tray :))

eric wrotefor automatization

like i said in the original post

bit wroteI suggest to use asoundconf(-gtk) to identify the hardware number before removing it

eric wrotethink about pulseaudio (i dislike it) for automatization

alsa is perfectly fine without *pulse(audio), it just takes a little tweak for surround sound users :D

eric wroteMay be write a little script to do the thing?

like i said.. asoundrc needs to be edited and not to direct itself to .asoundrc.asoundconf. for example this is my asoundrc.

# ALSA library configuration file

# Include settings that are under the control of asoundconf(1).
# (To disable these settings, comment out this line.)
# </home/taco/.asoundrc.asoundconf>

# for 5.1 speakers
pcm {
      type hw
      card 0
      device 0
} 

pcm.!default {
# # forwards to the mixer pcm defined below
    slave.pcm "dmix51"
    slave.channels 6
    type plug

# # "Native Channels" stereo, swap left/right
    ttable.0.1 1
    ttable.1.0 1
# # original normal left/right commented out
#    ttable.0.0 1
#    ttable.1.1 1

# # route "native surround" so it still works but weaken signal (+ RL/RF swap) 
# # because my rear speakers are more like random than really behind me
    ttable.2.3 0.7
    ttable.3.2 0.7
    ttable.4.4 0.7
    ttable.5.5 0.7

# # stereo => quad speaker "upmix" for "rear" speakers + swap L/R
    ttable.0.3 1
    ttable.1.2 1

# # stereo L+R => join to Center & Subwoofer 50%/50%
    ttable.0.4 0.5
    ttable.1.4 0.5
    ttable.0.5 0.5
    ttable.1.5 0.5
# # to test: "$ speaker-test -c6 -twav" and: "$ speaker-test -c2 -twav"
}

pcm.dmix51 {
	type dmix
	ipc_key 1024
# let multiple users share
	ipc_key_add_uid false 
# IPC permissions (octal, default 0600)
# I think changing this fixed something - but I'm not sure what.
	ipc_perm 0660 # 
	slave {
# # this is specific to my hda_intel. Often hd:0 is just allready it; To find: $ aplay -L 
		pcm "hw:0"
# this rate makes my soundcard crackle
#		rate 44100
# this rate stops flash in firefox from playing audio, but I do not need that
       rate 48000
       channels 6
# # Any other values in the 4 lines below seem to make my soundcard crackle, too
       period_time 0
       period_size 1024
       buffer_time 0
       buffer_size 4096
	}
}

eric wrotepeople normaly know how to do it

This is why I suggest to manually edit it themselves.
that's just my opinion..

eric wrotebut it is cool when some basic things like this are made automatically

again, I advised to remove asoundconf *after* identifying the hardware id, at least in that case configuring .asoundrc won't be as bad :) (and it saves the hw:? to retrovol anyway)

P.S My advise is for anyone with surround sound. So far the majority of obarun forum users installed obarun on laptops (which is 2 channel) thus it is perfect for most. it just needs manual configuration for anything else :)

edit: technically upstream for asoundconf verified dmix isn't (yet) implemented [0]
