Last night I gave a talk about LinuxTV at the local Michigan!/usr/group.
The slides can be found here:

The talk went quite well, and it’s always good to hear some feedback from the community as to what issues they are encountering (e.g. MythTV configuration, finding device firmware, debugging issues, etc.).
Glad to see you’re still at this. I decided to give one of the recent linuxtv mercurial builds a try with my HVR-950Q. Things worked much better watching LiveTV with MythTV and switching back and forth from analog to digital. The analog picture and sound was also much better since the last time I tinkered. I then decided to schedule a few back-to-back analog then digital recordings. That is when my old friends decided to show up in the syslog a few minutes into the third recording (second analog recording in the series):
Dec 16 21:01:21 stan kernel: ALSA sound/usb/usbaudio.c:354: frame 0 active: -18
Dec 16 21:30:15 stan kernel: recv_control_msg() Failed receiving control message, error -110.
Dec 16 21:31:14 stan kernel: au8522_writereg: writereg error (reg == 0xa4, val == 0x0020, ret == -5)
Dec 16 21:32:26 stan kernel: au8522_writereg: writereg error (reg == 0x106, val == 0x0001, ret == -5)
and so on and I had to reboot to correct the problem. Has there been any more progress on the HVR-950Q? I’d really love to start using it.
Well I finally managed to use ALSA (ALSA:hw:1,0) in MythTV instead of using the OSS emulation device (/dev/dsp1) and this seems to have done much better. My HVR-950Q is finally usable. Thanks very much for that!
Spoke too soon.. Eventually got the same errors using ALSA after many recordings.
