Re: [orca-list] ALSA Card Ordering [Was: I hate pulse]



Howdy,

sorry but that is just bullshit lol. Also PA does not choose an random sound card. it uses that one that you defined as default. You also can set output devices and prioritys by scripting or configuration like in alsa... so that argument is just wrong.

For me this is yet another reason to stay away from pulse. The last
thing I need with 5 sound cards is having some bot deciding which ones
should do what, and in what order. I have no use for machines that
ignore my specified configurations to make up their own.


In other words, this is just another way for things to break.

actually from what i know, pulseaudio does not go by ordering, but it
prioritizes cards based on type like internal card vs usb card vs
whatever... etc

Hi, John:

I noted one comment in your post re pulseaudio that I want to respond
to.

John G Heim writes:

devices are discovered in the same order. ...
No, but you can control the card order they're assigned, e.g. via
/etc/modprobe.d/alsa.conf using vid= and pid= params for multiple USB
sound cards.

The best on line summary of available approaches I've found to date is
at:

http://alsa.opensrc.org/MultipleCards

I'm currently working through the above as I have a nagging problem
every time I'm forced to reboot, e.g. after installing a new Linux
kernel.

My problem is that my hda device isn't always discovered. This morning I
ran a system update and had to reboot some 30 times before my Intel-810
hda device was discovered. I've looked in the logs. The problem is the
system is literally not seeing the device on most boots, yet once
loaded, it runs perfectly for days and weeks.

According to the above referenced article, there are approaches I might
try to resolve my problem without rebooting. And, it seems my current
ordering config code could be updated, too.

Nevertheless, I offer my current code because it does work to reliably
order my 5 sound devices. The always come up in the order defined below.
My only issue is whether, or not card 0 has been found, else the
remaining devices are shifted by 1--which doesn't help my situation as I
need the headset to match my configured FreeSwitch config, just as one
example.

<begin config file code>
alias snd-card-0 snd-hd-intel
options snd-card-0 index=0
options snd-hda-intel id=PCH index=0
alias snd-card-1 headset
options snd-card-1 index=1
options snd-usb-audio index=1 vid=0x1395 pid=0x3556
alias snd-card-2 cmedia
options snd-card-2 index=2
options snd-usb-audio index=2 vid=0x0d8c pid=0x000c
alias snd-card-3 ice
options snd-card-3 index=3
options snd-ice1724 index=3
alias snd-card-4 hdsp
options snd-card-4 index=4
options snd-hdsp index=4
<end config file code>
