[Linphone-developers] oss driver problem

[Yao-Chung Chang]

I use the ring program to test the oss driver, I can hear the ring tone

for a moment and got blocked with the following
messages

drop fragment when buffer gets too much data (xxxx -dicarded:xxx)
drop fragment when buffer gets too much data (xxxx -dicarded:xxx)
drop fragment when buffer gets too much data (xxxx -dicarded:xxx)
drop fragment when buffer gets too much data (xxxx -dicarded:xxx)


I've traced the code in oss_thread , and found it got blocked at

int sz = read(d->pcmfd, rtmpbuff, bsize);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

if (sz!=bsize) ms_warning ("sound device read returned %i !", sz);


Since ring didn't create any soundcard reader, why the snippet of code

just keep reading from the sound device?

As I know, oss has some problems, especially in embedded linux, how

do I solve this problem?
