Title:
USB sound card always reports as hw:1 (even if it is the only one)
Status in alsa-driver package in Ubuntu:
Expired
Bug description:
I have a system where the USB sound card is the only sound card in the system
(for good reasons).
I took me over an hour finding out why I have no sound. Then I found this in
/etc/modprobe.d/alsa-base.conf:
--- snip ---
# Keep snd-usb-audio from beeing loaded as first soundcard
options snd-usb-audio index=-2
--- snip ---
This line prevents my USB (and only) sound card to report as "card 0",
forcing it to report as "card 1" instead -- without any "card 0" being
present! To my understanding, sound cards in ALSA get enumerated
consecutively, starting with 0, and 0 being the "default card".
With this line in /etc/modprobe.d/alsa-base.conf, my system booted
with no default sound card present (although my USB card was plugged
in). And that is exactly what I got: no sound, and lots of headache.
I believe that this is a bug. It obviously is related to #46996, where
a user argues that he does not want his USB card to appear as card 0.
I strongly argue against this, at least if the USB card is the *only*
card in the system.
WHAT HAPPENS:
- I have a system with no internal/onboard sound card.
- I plug in a USB sound card and reboot.
- I have no sound at all. Alsamixer and other applications break, because
they cannot access the "default" sound card (i.e. card 0).
- After lots of reading and debugging (only feasible for advanced users), I
discover the line in /etc/modprobe.d/alsa-base.conf.
- After some more reading, I manage to create /etc/asound.conf to make card 1
the default.
- After that I have sound-
WHAT I EXPECT (and what happens in windows, and probably other OSes/distros):
- I have a system with no internal/onboard sound card.
- I plug in a USB sound card and reboot.
- I have sound.
I believe this is a bug that instantly drives not so advanced users
back to windows.
