LG has made audio in the line-out sense a priority for the G2. We’ve seen a lot of emphasis from other OEMs on speaker quality and stereo sound, with the G2 LG has put time into rewriting part of the ALSA stack and Android framework to support higher sampling and bit depth. The inability of the Android platform to support different sampling rates for different applications remains a big limitation for OEMs, one LG wrote around, and with the G2 up to 24 bit 192 kHz FLAC/WAV playback is supported in the stock player, and LG says it will make an API available for other apps to take advantage of this higher definition audio support to foster a better 24-bit ecosystem on Android.
I asked about what codec the G2 uses, and it turns out this is the latest Qualcomm WCD part, which I believe is WCD9320 for the MSM8974 platform. LG says that although the previous WCD9310 device had limitations, the WCD9320 platform offers considerably better audio performance and quality that enables them to expose these higher quality modes and get good output. The entire audio chain (software, hardware codec, and headphone amplifier) have been optimized for good quality and support for these higher bit depths, I’m told. I didn’t get a chance to listen to line out audio, but hopefully in testing this emphasis will play itself out in testing.
