Dieses Plugin empfängt den mit 16 bit kodierten Audio-Stream einer DVB-Karte und sendet ihn über den PCI-Bus an den S/PDIF-Ausgang einer vom ALSA-Treiber unterstützen Soundkarte.

- Support only VDR 1.6.0 and higher
- Scan always mpeg audio header in mad_frame_decode() as we work around the buffer guard internal of mad_header_decode()
- Do not delay first resulting PCM frame of mad_frame_decode()

- Add recording check to avoid to run into Add/DelPid trouble
- Use switching thread even for VDR 1.3.21+
- The ORF sample provided by a user has a large delay gap therefore do not timeout after 3 seconds.

- Add bug fix from Marcel Wiesweg in byte handle class
- Add thread locking class based on cThreadLock to get a non interrupted S/P-DIF forwarding in case of starting and
handling low state of the HW buffer of the sound card.
- Drop workaround on VDR Add/DelPid bug for ptOther and the handling on `Device or resource busy' because it breaks
replay part of the plugin.
- Start the live forwarding thread by attaching the receiver, requires a new logic to wait on the data stream and its type.
- Make MP2 Audio more synchron
- Be sure to store the correct name for PCMinitial
- Do not flood the syslog with mp2 messages if burst size is less than for layer II/III.

- Add nonlinear mp2 loop through S/P-DIF similar to AC3/DTS
- Use a frame based mp2 parser for libmad with buffer gard
- Make PCM initial wait frames configurable
- Remove Z680 option
- Remove MP2offset
- Add a workaround for broken sub audio header in PS1 payloads
- Be smarter in AV synchronization, wait on stable STC value
- Make xlist find plain AC3 in PS1 payload even from ORF

- Simply continue to get next pcm frame if PTS != STC
- Compare system clock delay with STC delay and only if both clocks are in sync we assume that STC is stable
- Switch back to frame repeat instead of sample repeat even for real audio.
- Try to solve delay detection to get the min start delay
- Don't repeat frames but stereo samples in case of audio
- Fix boolean cut&paste error in shm_malloc()
- Lock threads in Live Receiver and also in S/P-DIF forwarding thread.

- Use always cDevice::CurrentChannel() in ChannelSwitch() to be sure to get always the live channel on the primary card.
- Be sure that we do not get a SIGSEGV if terminated
- Add a further delay value for LiveTV
- Try out some DTS sanity checks
- Add some kernel version magic to shm_memory_tool
