Hi. I just tried to get sound working on a LinkSys NSLU2 (ARM) running Debian Etch using a USB sound card.
What I discovered I find pretty strange, and would like to know some more details. Apparently, all ALSA native clients don't manage to play sound click-free, they actually have underruns all the time. However, if I use OSS (via the snd-pcm-oss module) and set libao to use the oss driver, I get perfect playback with about 20% CPU use at maxiumum by the user-space app playing/decoding files. This is a bit strange, isn't it. OSS-emulation actually uses the same kernel code to access the actual hardware. I am just very vaguely familiar with the whole ALSA architecture, but it feels as if the problem here actually lies inside the user-space alsa libraries? Did anyone ever see such an effect, and investigate more closely what is the reason for the difference? -- CYa, Mario | Debian Developer <URL:http://debian.org/> .''`. | Get my public key via finger [EMAIL PROTECTED] : :' : | 1024D/7FC1A0854909BCCDBE6C102DDFFC022A6B113E44 `. `' `- <URL:http://delysid.org/> <URL:http://www.staff.tugraz.at/mlang/>
