[alsa-devel] wrong decibel data?

There's still no way to run the measurement with "pulse" because of
the previous error:Iteration 1, level is 0 (-inf dB).
   Volume level measured (0) was too high or too low.
   Please adjust mixer so that initial level is between 0.8 and 0.97.
   Test run canceled.
Are you sure that the test has sense using the pulse device?

"./dbmeasure plug:front plug_front.csv" works, but seems to never end:
   Iteration 3297, level is 0.0414072 (-27.6585 dB).
   Iteration 3298, level is 0.0414074 (-27.6584 dB).
   Iteration 3299, level is 0.0414064 (-27.6587 dB).
   Iteration 3300, level is 0.041406 (-27.6587 dB).

"./dbmeasure hw:0 hw.csv" fails with this message: "Cannot set sample
format: Invalid argument"
