Hi Ariff, could you please elaborate on what the difference between vol, ogain, and phout is? I'm asking this as I have problems with sound volume on my hardware and your comment is giving me the impression you commit might have fixed that. Symptoms: - vol only controls the loudness of my laptop speakers, pcm is still effective, ogain is ignored - plugging in headphones, ogain needs to be around 30-40, otherwise it is too loud - plugging in hifi equipment (with amplifier) I have to set ogain to 100 and pcm to near 100 to get acceptable loudness I think the hardware can sense the difference between headphone and other equipment, as I don't get that ogain-difference under windows. There, a headphone will sound equivalent to a connected hifi equipment. pcm0: <Intel ICH4 (82801DB)> port 0xb800-0xb8ff,0xbc40-0xbc7f mem 0xf4fff800-0xf4fff9ff,0xf4fff400-0xf4fff4ff irq 9 at device 31.5 on pci0 pcm0: <SigmaTel STAC9750/51 AC97 Codec> pcm0@pci0:31:5: class=0x040100 card=0x01911028 chip=0x24c58086 rev=0x01 hdr=0x00 vendor = 'Intel Corporation' device = '82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller' class = multimedia subclass = audio Have a nice weekend, Ulrich Spoerlein -- A: Yes. >Q: Are you sure? > >A: Because it reverses the logical flow of conversation. > >>Q: Why is top posting frowned upon?
