No sound for eac3 audio stream

No sound at all neither in live video nor in a recorded stream with eac3 audio. All stations that use this mode (e.g. ZDF) are affected. I am using the latest git version together with vdr 2.4.0 The recorded sample stream plays however nicely with ffplay, mplayer etc. It can be fetched from https://we.tl/t-LRpcZu7V4u until Jan 7 2019. The output from ffplay is 00001.ts': Duration: 00:00:11.00, start: 24534.765933, bitrate: 3332 kb/s Program 132 Stream #0:0[0x96a]: Video: hevc (Main) ([36][0][0][0] / 0x0024), yuv420p(tv, bt709), 1920x1080 [SAR 1:1 DAR 16:9], 50 fps, 50 tbr, 90k tbn, 50 tbc Stream #0:10x974: Audio: eac3 ([6][0][0][0] / 0x0006), 48000 Hz, stereo, fltp, 256 kb/s Stream #0:20x975: Audio: eac3 ([6][0][0][0] / 0x0006), 48000 Hz, stereo, fltp, 128 kb/s Stream #0:30x97f: Subtitle: dvb_subtitle ([6][0][0][0] / 0x0006) (hearing impaired) The various settings in vaapidevice (passthrough, downmix, tweaks) do not help.
