there was a patch https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda/patch_via.c?id=bc9b56238eedda865070dcaed6694d65b517c8d6
[ALSA] hda - Fix noise on VT1708 codec We get quite noisy output on the right channel on VT1708 codec when 24bit samples are used. Suppress the 24bit support until any real fix is found. seem the limitation seem removed by this patch ALSA: hda - Use generic parser for VIA codec driver https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda/patch_via.c?id=b3f6008f2d511133e0f04782c437a13b6865d26b -static const struct hda_pcm_stream vt1708_pcm_analog_s16_playback = { - .substreams = 1, - .channels_min = 2, - .channels_max = 8, - /* NID is set in via_build_pcms */ - /* We got noisy outputs on the right channel on VT1708 when - * 24bit samples are used.
