Yah, 2019-10-20 a guinea wore a hole through my pocket and fell down a sewer grate. =8~| https://en.wikipedia.org/wiki/Guinea_(coin) Ref. https://lists.debian.org/debian-user/2019/10/msg00743.html Subject: Re: Unidentified subject!

OK, although surround21:CARD=Set,DEV=0 and surround40:CARD=Set,DEV=0 aren't atomic names. Is the syntax and semantics explained in documentation? No surround22, surround23 ... surround39 evident here. How does ALSA derive or find the names and numbers? What is meant by CARD=Set? DEV=0 turns up frequently. What's the point? DEV=1? Incidentally, the AUDIODEV variable is a distraction. Rather than mess with it, specify the device directly. sox noise.WAV -t alsa plughw:CARD=ICH5,DEV=0 gain 1 Regards & thanks for the multiple earlier replies, ...
