[LAD] Audigy soundcard silent after upgrade to Ubuntu Studio

Problem solved by a contributor on LAU. He sent me a /var/lib/asound.state file from a working Audigy2 installation and, what do you know, it worked. There is a file that describes the state of the sound card in /var/lib/alsa/asound.state. When the original (bad) version was replaced with one from a working Audigy2 sound cared (good version) the card started working. The replacement asound.state file has 227 controls vs 216 for the oroginal. The following 14 switch controls existed only in the good file. The Master Playback Switch only existed in the good file. If it exists on the sound card and is muted by default, there would be no sound output. There are 3 possible duplicated controls. control.1 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Front Playback Switch' value.0 true value.1 true control.2 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Surround Playback Switch' value.0 true value.1 true } control.3 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'Center Playback Switch' value true } control.4 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'LFE Playback Switch' value true } control.5 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Side Playback Switch' value.0 true value.1 true control.7 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'CD Playback Switch' value.0 true value.1 true control.9 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Line Playback Switch' value.0 true value.1 true control.11 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Mic Playback Switch' value.0 false value.1 false control.12 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Front Mic Playback Switch' value.0 true value.1 true control.13 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Headphone Playback Switch' value.0 true value.1 true control.15 { comment.access 'read write' comment.type BOOLEAN comment.count 2 iface MIXER name 'Capture Switch' value.0 true value.1 true control.20 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'IEC958 Playback Switch' value false control.21 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'IEC958 Default PCM Playback Switch' value true control.22 { comment.access 'read write' comment.type BOOLEAN comment.count 1 iface MIXER name 'Master Playback Switch' value true ----------------- The following controls existed in both files.
