Maybe, but it does not matter.

Yes, it makes sense to add the card's longname and device number for fine device identification into description. I will do. > - All alises are shown.

I'll add configuration for other hardware soon. Here's output from my HDA machine: null Discard all samples (playback) or generate zero samples (capture) front:CARD=Intel,DEV=0 ALC880 Analog: Front speakers and multichannel output surround40:CARD=Intel,DEV=0 ALC880 Analog: Front speakers and multichannel output surround41:CARD=Intel,DEV=0 ALC880 Analog: Front speakers and multichannel output surround50:CARD=Intel,DEV=0 ALC880 Analog: Front speakers and multichannel output surround51:CARD=Intel,DEV=0 ALC880 Analog: Front speakers and multichannel output surround71:CARD=Intel,DEV=0 ALC880 Analog: Front speakers and multichannel output iec958:CARD=Intel,DEV=0 ALC880 Digital {Playback}: IEC958 (S/PDIF) Output spdif:CARD=Intel,DEV=0 ALC880 Digital {Playback}: IEC958 (S/PDIF) Output default:CARD=Intel ALC880 Analog: Default dmix+softvol + dsnoop device dmix:CARD=Intel ALC880 Analog: Direct sample mixing device dsnoop:CARD=Intel ALC880 Analog: Direct sample snooping device > My goal isn't for tools like aplay.

I'm sorry, but a click maybe a wrong click. I agree that we need to describe devices to be understandable for normal users, of course. Also, I would like to reorder devices in alsa.conf (like move default device as first etc.). Any objections?
