Currently, if the config file includes several hw_configs sections, parse_hw_config_refs() returns after parsing only the first section.

Applied. Thanks.

Jaroslav

For example, the following config, based on alsa-lib/src/conf/topology/broadwell/broadwell.conf, is parsed incorrectly:

SectionHWConfig."CodecHWConfig" {
        id "1"
        format "I2S"            # physical audio format.
        bclk   "master"         # Platform is master of bit clock
        fsync  "master"         # platform is master of fsync
}

SectionHWConfig."CodecHWConfig2" {
        id "2"
        format "AC97"
}

SectionLink."Codec" {

        # used for binding to the physical link
        id "0"

        hw_configs [
                "CodecHWConfig"
                "CodecHWConfig2"
        ]

        default_hw_conf_id "2"
}
