[SOLVED] Order of sound cards changes

gregors · 12-29-2019, 08:26 PM

Hi there!

My audio amplifier can act as an external sound card. But almost after every second (not just "sometimes") reboot it's not the first but second audio device - so I can't listen to my music or watch tv.

Since I tried a whole bunch of things with /etc/modprobe.d/alsa-base.conf I don't think that this is the right place to fix this.

Some years ago I found some kind of "the last, ultimative solution" which consists of entering the order of sound cards in a special file - the problem is I can't find that page again.

If you know what I'm talking about and know the solution ... I hate rebooting.

TIA

If you need further help, let us know the hardware (chipset and driver) details. For example...

Code:

lspci -nnk|grep -iA3 audio

Thanks!

After adding

Code:

options snd-usb-audio id=PCM2701 index=0
options snd_emu10k1 id=live index=1

to /etc/modprobe.d/alsa-base.conf and rebooting everything works fine. I hope this time it stays that way.

Glad to have been of guidance.

Unfortunately the order of soundcards in my configuration still changes from time to time. I still cannot turn on my PC and go to fetch some coffee - I have to stay and watch boot messages.

Here's my /etc/modprobe.d/alsa-base.conf:

Code:

# Added GS 26.12.19
#blacklist snd_hda_intel
#blacklist snd_ac97_codec
# Geaendert 3.12.19 GS, id hinzu am 30.12.19
options snd-usb-audio id=PCM2701 index=0
options snd_emu10k1 id=live index=1
# Added GS 26.12.19
#install snd-usb-audio
# autoloader aliases
install sound-slot-0 /sbin/modprobe snd-card-0
install sound-slot-1 /sbin/modprobe snd-card-1
install sound-slot-2 /sbin/modprobe snd-card-2
install sound-slot-3 /sbin/modprobe snd-card-3
install sound-slot-4 /sbin/modprobe snd-card-4
install sound-slot-5 /sbin/modprobe snd-card-5
install sound-slot-6 /sbin/modprobe snd-card-6
install sound-slot-7 /sbin/modprobe snd-card-7
# Cause optional modules to be loaded above generic modules
install snd /sbin/modprobe --ignore-install snd && { /sbin/modprobe --quiet snd-ioctl32 ; /sbin/modprobe --quiet snd-seq ; : ; }
install snd-rawmidi /sbin/modprobe --ignore-install snd-rawmidi && { /sbin/modprobe --quiet snd-seq-midi ; : ; }
install snd-emu10k1 /sbin/modprobe --ignore-install snd-emu10k1 && { /sbin/modprobe --quiet snd-emu10k1-synth ; : ; }
# Keep snd-pcsp from beeing loaded as first soundcard
options snd-pcsp index=-2
# Prevent abnormal drivers from grabbing index 0
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

Well, it seems Linux' best days are definitely over. I can't trust it to end up in the same state after turning on my computer anymore.

So ... what would you suggest to try now?

TIA

Gregor

Your manually configured audio drivers are

Code:

options snd-usb-audio id=PCM2701 index=0
options snd_emu10k1 id=live index=1

but your lspci output shows hardware using the 'snd_emu10k1' and 'snd_hda_intel' drivers. If you have USB audio hardware in the mix, you can get the chipset and driver details using

Code:

usb-devices

So best to provide the complete picture for further advice here.

BTW, an alternative way to configure sound card order manually involves using the 'pid=' and 'vid=' (vendor and product ID) options. For example...

Code:

options snd_emu10k1 index=1 vid=1102 pid=0002
options snd_hda_intel index=0 vid=10de pid=0be3

[Please ignore this posting. Just want to save what I wrote before rebooting. Is there a way to save a posting as draft?]

Oh my ...

Sorry if I mix things up and I caused unnecessary work.

So, here's what I have right now:

/etc/modprobe.d/alsa-base.conf

Code:

# Geaendert 1.1.20
options snd-usb-audio id=PCM2701 index=0 vid=08bb pid=2702
options snd_emu10k1 id=live index=1
#options snd_hda_intel id=? index=2 <------ what do I have to enter for id=?

# autoloader aliases

install sound-slot-4 /sbin/modprobe snd-card-4
install sound-slot-5 /sbin/modprobe snd-card-5

# Cause optional modules to be loaded above generic modules
install snd /sbin/modprobe --ignore-install snd && { /sbin/modprobe --quiet snd-ioctl32 ; /sbin/modprobe --quiet snd-seq ; : ; }
install snd-rawmidi /sbin/modprobe --ignore-install snd-rawmidi && { /sbin/modprobe --quiet snd-seq-midi ; : ; }
install snd-emu10k1 /sbin/modprobe --ignore-install snd-emu10k1 && { /sbin/modprobe --quiet snd-emu10k1-synth ; : ; }
# Keep snd-pcsp from beeing loaded as first soundcard

# Prevent abnormal drivers from grabbing index 0
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

'lspci -nnk | grep -iA3 audio' returns:

Code:

04:00.0 Multimedia audio controller [0401]: Creative Labs SB Live! EMU10k1 [1102:0002] (rev 07)
        Subsystem: Creative Labs SBLive! Player 5.1 [1102:8061]

        Kernel driver in use: snd_hda_intel

And 'usb-devices' results in (among other USB devices like keyboard and mouse):

I recommend you try something like the following

Code:

options snd-usb-audio id=PCM2701 index=0 vid=08bb pid=2702
options snd_emu10k1 index=1 vid=1102 pid=0002
options snd_hda_intel index=2 vid=10de pid=0be3

Quote:

what do I have to enter for id=?

I assume that can be got via

Code:

cat /proc/asound/card*/id

but probably just easier to use the vendor ID and product ID matching instead.

gregors · 01-01-2020, 03:50 AM

Your suggested options resulted in some "invalid value for parameter ...". And I remembered that I had to convert hex values to decimals when using such pid and vid values with qemu.

And it seems like vid and pid parameters are invalid for non-usb sound cards.

Well, now /etc/modprobe.d/alsa-base.conf reads:

Code:

# Geaendert 1.1.20
options snd-usb-audio id=PCM2701 index=0 vid=2235 pid=9986
options snd_emu10k1 id=live index=1
options snd_hda_intel id=NVidia index=2

#options snd-usb-audio id=PCM2701 index=0 #vid=08bb pid=2702
#options snd_emu10k1 id=live index=1 #vid=1102 pid=0002
#options snd_hda_intel id=NVidia index=2 #vid=10de pid=0be3

# autoloader aliases
install sound-slot-0 /sbin/modprobe snd-card-0
install sound-slot-1 /sbin/modprobe snd-card-1
install sound-slot-2 /sbin/modprobe snd-card-2
install sound-slot-3 /sbin/modprobe snd-card-3
install sound-slot-4 /sbin/modprobe snd-card-4
install sound-slot-5 /sbin/modprobe snd-card-5
install sound-slot-6 /sbin/modprobe snd-card-6
install sound-slot-7 /sbin/modprobe snd-card-7
# Cause optional modules to be loaded above generic modules
install snd /sbin/modprobe --ignore-install snd && { /sbin/modprobe --quiet snd-ioctl32 ; /sbin/modprobe --quiet snd-seq ; : ; }
install snd-rawmidi /sbin/modprobe --ignore-install snd-rawmidi && { /sbin/modprobe --quiet snd-seq-midi ; : ; }
install snd-emu10k1 /sbin/modprobe --ignore-install snd-emu10k1 && { /sbin/modprobe --quiet snd-emu10k1-synth ; : ; }
# Keep snd-pcsp from beeing loaded as first soundcard
options snd-pcsp index=-2
# Prevent abnormal drivers from grabbing index 0
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

and that seems to work.

Thanks again! Well, for now ... :-)

Gregor

Oh, BTW: Happy new year to all of you!

Now that I've checked further both 'modinfo snd-hda-intel' and 'modinfo snd-emu10k1' indeed don't appear to have the pid and vid options. My bad. Anyway, it looks like you've made progress here. The main thing is setting the explicit order of all audio devices that may be present.

gregors · 01-03-2020, 12:06 PM

Since there were no problems for the last 15-20 reboots I mark this thread as solved.

I hope I won't have to take this back :-)

ferrari · 01-04-2020, 05:57 PM

Now that the sound card order is explicitly configured, there should be no reason for any problems occurring.

Well, not *these* kind of problems, <german>gell</german> :-)))

Exactly.
