According to CTA 861 the channel/speaker allocation info in the audio infoframe only applies to uncompressed (PCM) audio streams. The channel count info should indicate the number of channels in the transmitted audio, which usually won't match the number of channels used to transmit the compressed bitstream. Some devices (eg some Sony TVs) will refuse to decode compressed audio if these values are not set correctly. To fix this we can simply set the channel count to 0 (which means "refer to stream header") and set the channel/speaker allocation to 0 as well (which would mean stereo FL/FR for PCM, a safe value all sinks will support) when transmitting compressed audio.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
