The TV tuner re-plays audio through the "mic" interface on my soundcard. It has worked for months, but now MythTV can't read anything from /dev/dsp. Any device that uses ALSA directly seems to work fine (like TVTime which plays TV with audio just fine) - only those that rely on /dev/dsp seem to have trouble. My simple test shows this: # cat /dev/dsp > /dev/null cat: /dev/dsp: Input/output error This was run as root. Perms are fine: crw-rw---- 1 root audio 14, 3 2008-10-03 08:56 /dev/dsp Myth user is in audio group (always has been). =20 Has something changed in ALSA that I didn't catch? I don't see anything in my logs or dmesg that shows a problem. My /etc/asound.conf is as follows: pcm.nforce-hw { type hw card 0 } pcm.!default { type plug slave.pcm "nforce" } pcm.nforce { type dmix ipc_key 1234 ipc_perm 0660 slave { pcm "hw:0,0" period_time 0 period_size 1024 buffer_size 4096 #rate 44100 rate 48000 } } ctl.nforce-hw { type hw card 0 } I have tried without this asound.conf and see the same issue. --=20 // Andrew MacKenzie | http://www.edespot.com // GPG public key: http://www.edespot.com/~amackenz/public.key // I've touch'd the highest point of all my greatness; // And from that full meridian of my glory // I haste now to my setting.
