This video demos a test setup using a Raspberry PI 2b, and a Behringer UCA222 usb sound card, to try and help stabilize the audio output from a CABLE TV box – keeping the volume the same, no matter how loud or soft each cable channel is…and being able to adjust the BASS, MIDS, and TREBLE to clarify speech…
NOTE: there was more than enough volume for the headphones I used to first test this setup, outputting from the UCA222’s headphone jack…which also has its own volume control – (full volume on the UCA222 headphone volume control was WAY too loud for me…but the extra volume available might be helpful for those with hearing deficits…and even if at full volume, it is still not enough for some with hearing deficits, a simple stereo audio headphone amp could be used, plugging into the Behringer UCA222’s LINE OUTPUT)
the audio you hear during the video is coming directly from the Behringer UCA222’s headphone jack to this recording laptop’s own usb sound card and then into the video so you can hear it…
the emphasis of this test was to see if this setup could be useful for those with hearing deficits…where the AGC and the EQ could be especially helpful when wearing headphones
the VOLUME of each cable channel stays very close to being the same using VLEVEL
