These days with the new and improved Mac OS X and macOS Sierra, on our MacWannaBe, \u00a0the speaker sound and mic don’t work after wake up from sleep. They come in many symptoms: no speaker after wake, plugin a headphone and pull out, the speakers work again or only failed when the AC charger plugged in and work with not plugged in.<\/em><\/p>\n

\u00a0 \u00a0 \u00a0\"Codec<\/a>\u00a0 \u00a0\"ALC255-ALC283,etc<\/a><\/p>\n

First we need to install EAPD (External Amplifier) codec-commander from Rehabman<\/a> – copy the\u00a0<\/em>hda-verb to \/usr\/bin<\/i><\/p>\n

sudo cp\u00a0<\/em>hda-verb \/usr\/bin<\/i><\/code><\/p>\n

Now if everything works with the sound then your codecs work with this EAPD codec-commander. If the kext is installed and it failed like described above, then you need to modify the info.plist in the kext itself. Change Perform Reset on EAPD Fail to TRUE.<\/em><\/p>\n

<key>Default<\/key>
\n<dict>
\n<key>Check Infinitely<\/key>
\n<false\/>
\n<key>Check Interval<\/key>
\n<integer>3000<\/integer>
\n<key>Custom Commands<\/key>
\n<array\/>
\n<key>Perform Reset<\/key>
\n<true\/><\/p>\n

<key>Perform Reset on EAPD Fail<\/key>
\n<true\/><\/p><\/blockquote>\n

<key>Perform Reset on External Wake<\/key>
\n<true\/>
\n<key>Send Delay<\/key>
\n<integer>300<\/integer>
\n<key>Sleep Nodes<\/key>
\n<true\/>
\n<key>Update Nodes<\/key>
\n<true\/>
\n<\/dict><\/p>\n

Look for your codec- mine is ALC255 and it uses alc283,etc modify perform reset to TRUE and change the delay from 10 to 300 also.<\/em><\/p>\n

<key>Perform Reset<\/key>
\n<true\/>
\n<key>Send Delay<\/key>
\n<integer>300<\/integer><\/p><\/blockquote>\n

<key>Sleep Nodes<\/key>
\n<false\/>
\n<\/dict><\/p>\n

Re-install the kext to S\/L\/E \u00a0with kext helper b7 to get it working. Now everything should work perfectly with the sound.<\/em><\/p>\n
