According to the block diagram of alc880 datasheet, it look like two mute
switches for node 0x02 and 0x0b or checkbox in hda_analyzer

Unfortunately hda_analyzer seem fail to parse your codec -info
File "./hda_analyzer.py", line 483, in <module>
sys.exit(main(sys.argv))
File "./hda_analyzer.py", line 460, in main
if read_nodes(sys.argv[1:]) == 0:
File "./hda_analyzer.py", line 110, in read_nodes
read_nodes3(card, idx, i)
File "./hda_analyzer.py", line 77, in read_nodes3
c = HDACodecProc(card, codec, proc_file)
File "/home/raymond/hda-analyzer/hda_proc.py", line 474, in __init__
self.parse(proc_file)
File "/home/raymond/hda-analyzer/hda_proc.py", line 678, in parse
node.add_ampvals(line[15:], HDA_INPUT)
File "/home/raymond/hda-analyzer/hda_proc.py", line 353, in add_ampvals
self.wrongfile('amp vals ]')
File "/home/raymond/hda-analyzer/hda_proc.py", line 143, in wrongfile
raise ValueError, "wrong proc file format (%s)" % msg
