[alsa-devel] dsnoop issues

[Gordon Miller]

Hi

All my snd_pcm_readi calls return too few frames. Also when I switch to 
stereo, the sound is muted. I cannot change this by adjusting period & 
buffer sizes. dsnoop is enabled by default. The documentation for 
snd_pcm_readi says that the only way that the frame count can be short 
is because of a signal or xrun. Well this clearly isn't the case.

I think that direct snoop is the cause of this. Are there any remedies ? 
because I am roundly SICK of being told that my application must be 
wrong "because everyone else's works". I have spent the last 3 weeks 
debugging an app - that always worked properly - because of the faulty 
dsnoop implementation.

It is abundantly clear that dsnoop is far from ready for use, but I am 
prepared to put some work into this.
Whose idea was it to enable dsnoop by default, when it doesn't even work 
? I was quite happy with OSS. Changing everything to be alsa entailed a 
lot of work, and I am beginning to think it was a complete waste of my time.
