Note: I was hoping that 2.0 fixed this issue but it persists. This issue does not pertain to RealTek ASIO, which has been blacklisted.
ASIO4ALL acts like a “wrapper” for the RealTek WDM drivers that make them behave like ASIO.
This issue began around 2022, after RealTek updated their Windows sound drivers that separate the headphones and speaker outputs. Before that, the headphone and speaker outputs were combined.
Issue: Headphone output is not engaged when using the current RealTek drivers and ASIO4ALL.
- Only use an older RealTek driver version 6.0.9254.1 dated 10/19/2021.
- Only use ASIO4ALL version 2.14 (version 2.15 is non-functional for JackTrip.)
Current RealTek drivers for Windows Sound have the speaker and headphone (if connected) configured as two separate outputs. When using ASIO4ALL 2.14, JackTrip does not engage the headphone output and only plays through the speakers.
A previous RealTek driver noted in my workarounds above, combines the speaker and headphone outputs. ASIO4ALL v.2.14 and JackTrip successfully engage the headphones when connected and speaker outputs as needed.
With the current RealTek drivers that separate the headphone and speaker output and ASIO4ALL 2.14:
a. JackTrip does not engage with the headphone and only plays through the speaker, even when the headphone is plugged in and selected.
b. In the VS settings, when tapping “Test Tone”, there is signal but no sound in the headphones, only the speaker. There is no change when selecting headphones in the Windows sound settings.
c. In VS settings, when changing to output 3&4, and tapping “Test Tone”, there is sound in the headphones. However, when in the studio interface, there is still no sound in headphones.
d. The settings in ASIO4ALL accommodate 2 channels for the speakers as per the RealTek driver. There is another output labeled, “2nd Output”. This could be the headphone output, which RealTek has as a separate output. JackTrip’s output protocol for headphones is not finding it as a second output, but rather possibly as channels 3&4.
