No way to switch sound cards under Lenny

frenchn00b · 07-27-2009, 02:44 AM

I have

Code:

# cat /proc/asound/cards
 0 [default        ]: USB-Audio - AK5370          
                      AKM              AK5370           at usb-0000:00:02.1-2, full speed
 1 [default_1      ]: USB-Audio - PnP Audio Device        
                      PnP Audio Device         at usb-0000:00:02.1-4, full speed

I want/need to have sound, by any ways:

Code:

# cat /proc/asound/cards
 0 [default     ]: USB-Audio - PnP Audio Device        
                      PnP Audio Device         at usb-0000:00:02.1-4, full speed
 1 [default_1         ]: USB-Audio - AK5370          
                      AKM              AK5370           at usb-0000:00:02.1-2, full speed

my dmesg indicates:

the prob is that a boot, it loads first hte moduels for hte AK5370 of the microsophone usb

asound.conf is not present anymroe under lenny

what a mess linux and sound.
it could be made easy

TITiAN · 07-27-2009, 05:45 AM

You can still create the /etc/asound.conf or ~/.asoundrc file and write its contents by hand. You can even make ALSA apps use a sound interface by defining it via an environment variable. If you want me to write such a file, post the output of the command "aplay -l" here and I'll explain how to use it etc. .

wow you are talented!

so here the output:
cat /proc/asound/cards

Code:

 0 [default        ]: USB-Audio - AK5370
                      AKM              AK5370           at usb-0000:00:02.1-1, full speed
 1 [default_1      ]: USB-Audio - PnP Audio Device
                      PnP Audio Device         at usb-0000:00:02.1-4, full speed

I would liek to swap the default and default_1.

(I have to reboot to do aplay)

TITiAN · 07-27-2009, 09:02 AM

Oops, not "cat /proc/asound/cards", it's "aplay -l"

milomak · 07-27-2009, 04:00 PM

In /etc/modprobe.d/alsa-base.conf you have a line like

Code:

options <snd-driver-for-AK5370> index=-2

the index=-2 part basically tells the system not to load the card as the first card

frenchn00b · 07-28-2009, 01:08 AM

still not working

Code:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 1: default_1 [PnP Audio Device        ], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I also tried this:
cat /etc/modprobe.d/alsa-base

Code:

...
install snd-wavefront /sbin/modprobe --ignore-install snd-wavefront $CMDLINE_OPTS && /lib/alsa/modprobe-post-install snd-wavefront
# Prevent abnormal drivers from grabbing index 0
options ohci_hcd index=-2
#options bt87x index=-2
#options cx88_alsa index=-2
#options snd-atiixp-modem index=-2
options snd-intel8x0m index=-2
options snd-via82xx-modem index=-2
# Keep snd-pcsp from beeing loaded as first soundcard
options snd-pcsp index=-2

Oh I notice that both cards are USB so both probably using snd-usb-audio. The the /etc/asound.conf or ~/.asoundrc solution is what will most likely work

Here is how I have used /etc/asound.conf on my MythTV box to make the card that is not first to be used

Code:

mythtv@mythtv-debian:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: HDA Generic [HDA Generic]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Code:

mythtv@mythtv-debian:~$ cat /etc/asound.conf
   pcm.!default {
       type hw
       card 0
       device 3
   }

  pcm.!default {
     type plug
     slave.pcm "hdmi"
  }

do a google search for asoundrc or asound.conf for a better understanding of how to use it.

This should set you in the right direction
