So far, Alsa has given extremely mixed results. As I stated, I had to go back to beta 12. Some sounds sound better than with the stock drivers and some have a loud pop or squeal at the end. Next, the whole thing about muting all channels by default is absolutely insane. I had my /etc/modules.conf set up to auto-load Alsa and after a short time, the modules unload and when they reload, everything is muted again. I got around this by manually loading the modules in /etc/rc.d/rc.modules so that they stay in memory. I'll probably leave it that way anyway as it's faster. Anyway, all this has been a let down when it comes to Speak Freely. I've tried both the stock 7.2 and the CVS version and had very unsatisfying results. Both versions work fine in half duplex, but I may as well use the stock drivers if I have to use half duplex. When trying full duplex, a person reported that I was sending dead carrier. Further testing with an echo-back server reveals that what is happening is that I send out a long period of silence then audio. Finally, it is as if the last packet gets held up until I close the connection. When I kill sfspeaker, I will get a burst of sound like the last part of a word and then all sounds I play will play about half speed with a horrible clicking over the top. It's like the old APH tape recorders that claimed to let you adjust the speed and keep the pitch sounding the same. They produced a very similar sound. In other words, Speak Freely is messing up Alsa. I've tried every combination from the default flags to the -DLINUX_SMALL_BUFFER flag and removing the -DAUDIO_BLOCKING flag which produced noise instead. With the stock driver, I could sort of get full duplex with the sflaunch front-end, but after a few minutes, incoming audio would start breaking up and get progressively worse until becoming unusable. Sflaunch doesn't seem to work at all with Alsa most of the time. Also, with the stock drivers, I got a log of recording overruns even when I wasn't talking. The bottom line is I've never gotten satisfactory performance from the Unix/Linux version of Speak Freely. I thought Alsa would be the solution, but I'm just about to go back to the stock driver and live with half duplex. If anybody has actually gotten Speak Freely working with an AW64 in full duplex mode, regardless of what drivers they used, I'd like to hear about it!
