The main problem is that many laptop's soundcards are basically crappy, and if you're going to use your laptop for serious audio work, it's probably best to get, either a USB soundcard, or a pcmcia one. Anyway. This is what Lee Revell posted back to me. My comment. > > The hda-intel driver is supported according to the sound card matrix, but are > there any odd problems with it?

It's misleading to say "snd-hda-intel is supported" because every single laptop and motherboard with snd-hda-intel is slightly different and there's absolutely no documentation on what the differences are. Possibly the hardware is oncorrectly detected. It's also possible that these devices simply have no hardware master volume and Windows emulates it in software. All these users can do for now is search for information about their machine in the ALSA bug tracker and hope it gets fixed someday. (They can also try the various model options for their codec described in Documentation/ALSA-Configuration.txt). Lee And a further post from Lee. My posting of your amixer output. > ------- amixer -------- > Simple mixer control 'PCM',0 > Capabilities: pvolume > Playback channels: Front Left - Front Right > Limits: Playback 0 - 255 > Mono: > Front Left: Playback 255 [100%] > Front Right: Playback 255 [100%] > Simple mixer control 'Front',0 > Capabilities: pvolume pswitch > Playback channels: Front Left - Front Right > Limits: Playback 0 - 31 > Mono: > Front Left: Playback 31 [100%] [on] > Front Right: Playback 31 [100%] [on] Since you only seem to have 2 channels, doesn't "Front" work as a master? Lee. Sorry that I couldn't bring you any good news. Nigel.
