The problem is that due to the very nature of bug reporting I have a good idea what doesn't work but not so much about what works. Generally I'd stick to UAA hardware: http://en.wikipedia.org/wiki/Universal_Audio_Architecture I.e. that's HDA which should mostly be supported very well. Some implementations are flakier than others, but if you want something that is PCI then this is generally a good choice. HDA is usually built into mainboards, not sure if you can get non-mainboard cards. The predecessor of HDA, i.e. chips that implement something that works with the intel8x0 driver are probably a good choice too, if the bug pointed out in this thread gets fixed: http://mailman.alsa-project.org/pipermail/alsa-devel/2009-February/014929.html The other option is USB. That works quite well, although the driver has some issues regarding the accuracy of the timing. That might affect applications that rely on stable timing alhtough PA should work fine with this. Picking a USB card from a well-known vendor is probably a good idea, since they tend to implement the USB interface more correctly and stuff like dB reporting might be available which is something cheap devices usually don't get right. The Firewire cards are probably no good choice on Linux. 1394 on Linux is a bit of a chaos and they are not supported in ALSA. One last thing: I don't give guarantees: take what I wrote above as a hint, but you get no warranty on this. ;-) Lennart -- Lennart Poettering Red Hat, Inc. lennart [at] poettering [dot] net ICQ# 11060553 http://0pointer.net/lennart/ GnuPG 0x1A015CC4
