  1. There is an issue in AudioCapabilities.java getMaxSupportedChannelCountForPassthrough(). The function iterates from DEFAULT_MAX_CHANNEL_COUNT, which now is 10 to 1 and trying to create AudioFormat, setting the channel mask with given channel count, but Util.getAudioTrackChannelConfig() for input parameter 9 returns AudioFormat.CHANNEL_INVALID, which leads to exception.

The issue happened after May 25 2023, when DEFAULT_MAX_CHANNEL_COUNT was changed from 8 to 10.

The possible fix:
