Comment # 11 on bug 1214163 from Nathan Wolf

I am a bit confused on what you want me to do with this:

/proc/asound/card/*/eld#*

"card" is a file and the output for each is this:

Framework:
 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0x605d1c0000 irq 184

EliteBook:
 0 [sofhdadsp      ]: sof-hda-dsp - sof-hda-dsp
                      HP-HPEliteBook840G7NotebookPC--8723

But that doesn't seem like what it is that you want.
