Hi im using a fujitsu siemens liteline lap with linux suse 7.1, everything goes fine here after some trouble configuring the graphic adapter (trident cyberblade). Im sure this isn't the ideal laptop for making music... but im really happy, latency is unnoticeable, and can use reasonably complex patches without getting the CPU meter too far up(AMDK6II), in fact i have never experienced cpu performance problems even running fairly CPU consuming patches like the phase vocoder in the /doc directory or a fairly complex "granular workshop" im working at. Not like in my wndws setups where working with audio is not possible as i get a huge latency and continuous clicks and pops. The only 'problem' i have is that i get occasional clicks when making sound and redrawing arrays simultaneously, but i think this was a general issue, am i right? I think somebody had a workaround for this running two pd instances one without graphic interface and the other without sound communicating via netsend (is this documented somewhere? i couldnt get it working)
My lap has also a built-in soundcard ESS maestro 3 (number 1870 i think), but in my case i/o is limited to just 1 mono input and stereo out (the output quality isnt too bad). Sometimes i have experienced problems with the fan: a couple of times when outputting sound & the fan started, pd seemed to freeze and the whole system slows down to snail speed during 4 or 5 minutes (the terminal reports 'signaling pd') and then back to normal. The problem goes away deactivating autofan in the bios (which frightens me a little). Somewhere i saw a message where somebody claimed that there were some laptop models where this could not be done so watch this.
Also i get occassional dac errors (IO stuck etc.. ) when using alsa drivers, so i use alsa's oss emulation preferably. OSS drivers went fine after a little experimentation with -frags flag. -frags didnt seem to do anything when using alsa so maybe there is a kind of tuning flag i could fiddle around with for alsa drivers too?
Im looking forward to getting some better i/o too. I heard about hamerfall PCMCIA, and Ego-Sys PCMCIA (?), but the shop won't let me test before buying so im a little frightened to buy before hearing about more people running similar setups succesfully. I thought i heard somewhere firewire wasnt the way to go yet in linux as it is little supported, or is somebody linux-laptop-sound-firewiring out there? I think some soundcards' alsa drivers cant get audio & midi working together o am i wrong again? (i would really like to twist my patches).
By the way, be careful ... laptop+pd = total pd addiction.

hi
Is there anybody in the list who uses a notebook (PC) for creation of
sound
? I`d like to buy one for mobility but can not find any answer on the
question
of quality of sound. In specifications for some notebooks stands only "SBpro compatible stereo sound" comment. I dont know what does it mean, becouse it's just driver-standart, no more. Would it be enough quality (of a soundcard) for making sound? Have any experience?
Thanks. Andrey.
