Yes, you should give your brain some rest and don't lose sleep over
this:)
But I really guarantee you that the only information that LMS gets from
the bridge is the "<sample_rate>" parameter. The parameters associated
with "<mode>" are never transmitted to LMS. I will run some test and
look at LMS code to see how it does downsampling decisions, but the
"48000" information is never leaked out to LMS. All happens in this log
line
Code:
--------------------
[...] sendHELO:124 [0x64b700] cap:
Model=squeezelite,ModelName=SqueezeLite,AccuratePlayPoints=1,HasDigitalOut=1,MaxSampleRate=192000,flc,pcm,mp3
--------------------
The "MaxSampleRate" is the "<sample_rate> parameter of the config file,
per this line of code in slimproto.c
Code:
--------------------
sprintf(ctx->fixed_cap, ",MaxSampleRate=%u,%s", ctx->config.sample_rate,
ctx->config.codecs);
--------------------
And this is only sent when the player first registers to LMS
