Udo Erdelhoff:
 |I've used a small shell script to get "The Big Picture"(tm)
 |#!/bin/sh
 |A=0
 |while [ $A -le 100 ]; do
 |	mixer vol $A
 |	mixer
 |	A=`expr $A + 1`
 |done
 |
 |The result is consistent for all mixer devices:
 |Input Value	Output Value
 |0		 0
 |1		 4
 |2		 4
 |3		 4
 |4		 7
 |5		 7
 |6		 7
 |7		10
...
 |And that's the reason for the original poster's problem: fxtv reads the
 |mixer setting and writes it back. And that's enough to increase the volume
 |to max with just 32 cycles...

 |Config details:
 |
 |Kernel config: device pcm
 |FreeBSD 5.0-CURRENT #7: Thu Mar 30 07:45:57 CEST 2000
 |pcm0: <AudioPCI ES1371> port 0xe000-0xe03f irq 5 at device 9.0 on pci0

Glad that you got it tracked down.  Now the question is who maintains the
ES1371 PCM driver.
