My question was about your sentence: "All period sizes must be equal". Is it true ? It seems quite strange to me because ALSA passes a buffer size that is not multiple than the period size almost always. This is not a problem in my case because the s-g list is generic enough to handle it. -- Giuliano. ------------------------------------------------------- This SF.Net email is sponsored by: Oracle 10g Get certified on the hottest thing ever to hit the market...
