Research direction

Start with sound/soc/bcm/rpi-simple-soundcard.c, especially the drvdata_merus_amp and snd_merus_amp_dai definitions shown in the issue. Trace how .card_name becomes the Roon-visible card name and assess whether .name or .stream_name can provide an override or prettier display; done means identifying a supported change or documenting why it is not possible.

Description

Currently when using RoonBridge running on a pi, it pulls in the .card_name parameter as the name of the card in Roon:

For example the above is pulling from this code:

static struct snd_rpi_simple_drvdata drvdata_merus_amp = {
	.card_name        = "snd_rpi_merus_amp",
	.dai              = snd_merus_amp_dai,
	.fixed_bclk_ratio = 64,
};

Is there a way to override what is shown here? Or make it "prettier"? For example it would be nicer if we could display the .name or .stream_name from above:

static struct snd_soc_dai_link snd_merus_amp_dai[] = {
	{
		.name           = "MerusAmp",
		.stream_name    = "Merus Audio Amp",
