can this be reproduced on other HDA codec with different dB per step or just
specific to alc892 which has 1 dB per step ?
Node 0x02 [Audio Output] wcaps 0x41d: Stereo Amp-Out
Device: name="ALC892 Analog", type="Audio", device=0
Control: name="Front Playback Volume", index=0, device=0
ControlAmp: chs=3, dir=1, idx=0, ofs=0
Amp-Out caps: ofs=0x40, nsteps=0x40, stepsize=0x03, mute=0
Amp-Out vals: [0x14 0x15]
do all sound card need deferred volume enabled ?
CONFIG_SND_HDA_PREALLOC_SIZE=64
your HDA max buffer seem to be 64 KBytes instead of 4096 Kbytes</pre>
