Tried ]$ play ~/Music/babycry.wav play formats: can't open input file `/home/bill/Music/babycry.wav': Unhandled WAV file encoding (MP3). Try overriding the encoding: e.g. for an MP3 WAV, `-t mp3' ]$ play -t mp3 ~/Music/babycry.wav play formats: no handler for given file type `mp3' -- no sound. That is OK, I'll chase your advice down a little. e.g. questions like "Why is a .wav not a .wav?" Thank you for introducing me to sox. I had never heard of it before. I have been having trouble with sound ever since I bought a new box in November? Audio Chip/Device product: 82801G (ICH7 Family) High Definition Audio Controller [8086:27D8] vendor: Intel Corporation [8086] bus info: pci@0000:00:1b.0 version: 01 width: 64 bits clock: 33MHz capabilities: Power Management, Message Signalled Interrupts, PCI Express, bus mastering, PCI capabilities listing configuration: driver: HDA Intel latency: 0 There is no further point that I can see trying to fix anything until the HDA driver or whatever else needs to be fixed is fixed. I have made no headway on this list (although I have received losts of helpful suggestions), the ALSA users list or Fedora bugzilla. -- Regards Bill Fedora 11, Gnome 2.26.3 Evo.2.26.3, Emacs 23.1.1 -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
