Recovery from muting is instant even with very large DC blocking capacitors. The ISL54406 also has comprehensive click and pop elimination measures to prevent these artifacts from occurring in the load due to system power-up/power-down, codec enable/disable, headphone hot plug-in, and audio muting on/off situations. The click and pop elimination is effective in low and high impedance loads and requires no external timing components to deal with DC blocking capacitors placed between the single supply codec and the load.
