Package: firmware-misc-nonfree
Version: 20221012-1
Severity: normal

Dear Maintainer,

I have been running into weird behaviour on my Creative Labs Sound Blaster Z (Serial number either SB1500 or SB1502).
Just now I noticed that a seemingly related firmware file doesn't get loaded.
Here is a section out of dmesg:

[    9.591329] snd_hda_intel 0000:02:00.0: firmware: failed to load ctefx-desktop.bin (-2)
[    9.591355] firmware_class: See https://wiki.debian.org/Firmware for information about missing firmware
[    9.591387] snd_hda_intel 0000:02:00.0: firmware: failed to load ctefx-desktop.bin (-2)
[    9.591409] snd_hda_intel 0000:02:00.0: Direct firmware load for ctefx-desktop.bin failed with error -2
[    9.592599] snd_hda_intel 0000:02:00.0: firmware: direct-loading firmware ctefx.bin

ctefx-desktop.bin shows up in the list of firmware that is supposed to be included in Debian. https://wiki.debian.org/Firmware/List

While the driver seems to load a different firmware file, and the sound card works most of the time, the identification in lspci seems wrong, and there is random issues like no audio output until reboot, "electric" audio output until reboot, no audio input until reboot, settings needing to be applied multiple times, and alsactl store failing.
lspci reports a "Subsystem: Creative Labs SB1570 SB Audigy Fx", while this card is from a different series and looks completely different from it.
Not knowing much about this sort of thing, I am assuming the driver is falling back to the firmware for a different sound card, which might be causing a bunch of my issues.
