Pulse has been uninstalled, then uninstalled ALSA en reinstalled. Nothing, but ... noticed a small noise, running speaker-test and after putting the host at full sound, discovered a broken (pink) noise output of speaker-test. By the way, the "pipe quebrado" in the amixer output in my previous message means "broken pipe". Tested some youtube videos ramdonly and always a broken sound. So, amixer's logs tranlate accurately what is heard. Pulse was not the source of problems, apparently. Strace output is similar to amixer: speaker-test 1.0.21 Playback device is default Stream parameters are 48000Hz, S16_LE, 1 channels Using 16 octaves of pink noise Rate set to 48000Hz (requested 48000Hz) Buffer size range from 32 to 32768 Period size range from 32 to 32768 Using max buffer size 32768 Periods = 4 was set period_size = 8192 was set buffer_size = 32768 ... ioctl(4, 0x400c4150, 0xbf977d84) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = -1 EPIPE (Broken pipe) write(2, "Write error: -32,Pipe quebrado\n"..., 31Write error: -32,Pipe quebrado ) = 31 ioctl(4, 0x4140, 0) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = -1 EPIPE (Broken pipe) write(2, "Write error: -32,Pipe quebrado\n"..., 31Write error: -32,Pipe quebrado ) = 31 ioctl(4, 0x4140, 0) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = -1 EPIPE (Broken pipe) write(2, "Write error: -32,Pipe quebrado\n"..., 31Write error: -32,Pipe quebrado ) = 31 ioctl(4, 0x4140, 0) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = 0 ioctl(4, 0x400c4150, 0xbf977d84) = 0 gettimeofday({1253848581, 711401}, NULL) = 0 write(1, "Time per period = 0,129907\n"..., 27Time per period = 0,129907 ) = 27 gettimeofday({1253848581, 715393}, NULL) = 0 write(1, " 0 - Front Left\n"..., 16 0 - Front Left ) = 16 Thanks again []s, Fernando Oliveira Natal, RN, BRAZIL ____________________________________________________________________________________ Veja quais são os assuntos do momento no Yahoo! +Buscados http://br.maisbuscados.yahoo.com -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
