Thank you for testing this. Looks like we cross posted. I found setting the outputThreshold to 20 gives a quicker startup and still prevents the underrun. Need to do more testing with that server side change with all the aac content that played fine before changing it. Hence my comments about no real need for the downmix feature for the radio. I couldn't hear any difference between the bass driver and tweeter with it set to stereo or mono output channel mode. But if I add it to the community firmware I didn't want the change to be in one and not the others, just too confusing. Other than those 2 patches, the difference between the previous test static jive and the stutterfix jive is the stutterfix does NOT have fdk-aac linked static, which is the same as the jive binary included in r18635. I haven't seen/heard the "POP" issue with any of the 3 jive binaries. Very strange.
