[alsa-devel] dB range of emu10k1 hda-intel
2011/4/26 Takashi Iwai tiwai@suse.de
Is it a bug for PA server to add TLV_DB_GAIN_MUTE - infinite dB range of "Front" and "Surround" and those finite dB range of "Master" and "PCM" ?
Hrm, not sure. Could you elaborate?
Should the application add the dB range of Virtual Master and the dB range of the slave for HDA-Intel ?
Correct me if I am wrong
PA server seem use -168.00 dB to 0.00 dB. for hda-intel
For ad1988 spec->vmaster_nid = 0x04;
"Virtual Master" + "Front" + "PCM Softvol" = 58.5 + 58.5 + 51 = 168

The dB range of emu10k1 calculated by PA server is (-100081dB to +12 dB)
"AC97 Master" + "AC97 PCM" + "Front" = 46.5 + 46.5 + 99999.99 = 100093
