I can play succesfully each of the following substreams:

static struct snd_soc_dai_link omap3baia_dai[] = { { .name = "TLV320AIC31", .stream_name = "AIC31", .cpu_dai_name = "omap-mcbsp-dai.3", .codec_dai_name = "tlv320aic3x-hifi", .platform_name = "omap-pcm-audio", .codec_name = "tlv320aic3x-codec.2-0018", .init = omap3baia_tlvaic31_init, .ops = &omap3baia_tlvaic31_ops, }, { .name = "TWL4030", .stream_name = "TWL4030", .cpu_dai_name = "omap-mcbsp-dai.1", .platform_name = "omap-pcm-audio", .codec_dai_name = "twl4030-hifi", .codec_name = "twl4030-codec", .init = omap3baia_twl4030_init, .ops = &omap3baia_twl4030_ops, }, };

I have also some analog connections between TWL4030 and TLV320AIC31 and I'd like to create an automatic audio path (for example from TWL4030 HFL to TLV320AIC31 LINE2L), but I obtain "Failed to add route Virtual Tps to Tlv->LINE2L"

static const struct snd_soc_dapm_route audio_map_twl4030[] = { {"Virtual Tps to Tlv", NULL, "HFL"}, /* from tps to tlv */ {"LINE2L", NULL, "Virtual Tps to Tlv"}, /* from tps to tlv */ };

Because LINE2L is obviously defined inside TWL4030 codec.

static const struct snd_soc_dapm_widget dapm_widgets_twl4030[] = { SND_SOC_DAPM_OUTPUT("Virtual Tps to Tlv"), };

Is there a clean way to manage this situation? I have also tried without "Virtual Tps to Tlv" but the problem is the same.

Thx, Raffaele
