transcoding FLAC to DLNA-approved (LPCM or mp3)

I have a BD670 BR player and I also have over 700 CDs ripped to FLAC. I would like to stream them to my player from Serviio, but every time it says "Audio format not supported." I set the profile to LG within the Serviio console, but no dice. Can someone help? Here is the DeviceSpy spec:

http-get:*:audio/l16;rate=44100;channels=1:DLNA.ORG_PN=LPCM,http-get:*:audio/l16;rate=44100;channels=2:DLNA.ORG_PN=LPCM,http-get:*:audio/l16;rate=48000;channels=1:DLNA.ORG_PN=LPCM,http-get:*:audio/l16;rate=48000;channels=2:DLNA.ORG_PN=LPCM,http-get:*:audio/mpeg:DLNA.ORG_PN=MP3,http-get:*:image/jpeg:DLNA.ORG_PN=JPEG_SM,http-get:*:image/jpeg:DLNA.ORG_PN=JPEG_MED,http-get:*:image/jpeg:DLNA.ORG_PN=JPEG_LRG,http-get:*:video/mpeg:DLNA.ORG_PN=MPEG_PS_PAL,http-get:*:video/mpeg:DLNA.ORG_PN=MPEG_PS_NTSC,http-get:*:video/vnd.dlna.mpeg-tts:DLNA.ORG_PN=MPEG_TS_SD_NA,http-get:*:video/vnd.dlna.mpeg-tts:DLNA.ORG_PN=MPEG_TS_SD_NA_T,http-get:*:video/mpeg:DLNA.ORG_PN=MPEG_TS_SD_NA_ISO,http-get:*:video/vnd.dlna.mpeg-tts:DLNA.ORG_PN=MPEG_TS_SD_KO,http-get:*:video/vnd.dlna.mpeg-tts:DLNA.ORG_PN=MPEG_TS_SD_KO_T,http-get:*:video/mpeg:DLNA.ORG_PN=MPEG_TS_SD_KO_ISO,http-get:*:video/vnd.dlna.mpeg-tts:DLNA.ORG_PN=MPEG_TS_SD_EU,http-get:*:video/vnd.dlna.mpeg-tts:DLNA.ORG_PN=MPEG_TS_SD_EU_T,http-get:*:video/mpeg:DLNA.ORG_PN=MPEG_TS_SD_EU_ISO,http-get:*:audio/mpegurl:*,http-get:*:audio/mp3:*,http-get:*:audio/wma:*,http-get:*:audio/x-ms-wma:*,http-get:*:audio/mp4:*,http-get:*:audio/mpeg:*,http-get:*:audio/wav:*,http-get:*:audio/mpeg3:*,http-get:*:video/x-ms-avi:*,http-get:*:video/mpeg:*,http-get:*:video/avi:*,http-get:*:video/mp4:*,http-get:*:video/x-matroska:*,http-get:*:video/quicktime:*

The BD670 BR player does not support FLAC so you will need to transcode your audio. To do this, edit your profiles.xml file (see here) and add the following to the "LG TV / player" section (add it just before the <HardSubsTranscoding> line):

  Code:

<Audio targetContainer="lpcm" forceInheritance="true">
     <Matches container="flac" />
</Audio>

After editing and saving the profiles.xml file, restart your PC for this to take effect (or restart the Serviio service if you know how to do this). I have transcoded to lpcm but you may prefer a different format. You may also wish to add other unsupported audio types if required (look at the Sony Bravia TV (2012) profile as an example).
