Message-ID: <20020410142953.A20650@gehtnix.fernuni-hagen.de> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: owner-linuxppc-dev@lists.linuxppc.org List-Id: Hi, I just compiled linphone for linux ppc on a 2.4.18 benh kernel succesfully, and was able to connect to a second linphone on another computer, though there has been no voice transmission. After a small discussion with the developer of linphone he wondered about the high latency of the sound card. > > Warning: dsp block size set to 16384. > OUCH !! 16386 bytes is very very high latency ! Your sound card is > perhaps very old, or the driver is not very performant ! > I've never see that. The most I had was 8192. > Recent PCI cards give 512 bytes. This was done on a Pismo. I wonder if the block size is normal for a Pismo or if this could be the reason for the lack of voice transmission.
