List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: video4linux-list-bounces@redhat.com Errors-To: video4linux-list-bounces@redhat.com List-ID: I forget if I've already mentioned this yet... I recently started playing around with analog NTSC television again on my system, while trying to help someone solve a problem on their system. In the process I ran into a problem getting cx88-alsa to build with the rest of the v4l-dvb repository. As it turned out, mine was one of the stock Ubuntu kernels that have some odd issue with the I2C configuration. I had to build a vanilla kernel (2.6.26.5), making all the I2C stuff into modules as opposed to built-in. So, that's fixed - cx88-alsa builds and loads OK now. However, I have a new problem: Something has broken the output that cx88-alsa creates. In the case of my Kworld ATSC 120, radio output on all frequencies has a sort of growling "industrial" noise on top of the actual audio, kinda like the background noise of a manufacturing facility. Analog TV on all channels gives clean but very tinny audio, as though the sample rate were really low (~8kHz). Since other audio sources are working fine, I can't tell if this is a bug in the kernel, or cx88-alsa, or something else entirely. I've only noticed the problem for a matter of a week or less, so I'm not sure when it started. The problem persists as of today's pull of the v4l-dvb repository. -- "Life is full of positive and negative events. Spend your time considering the former, not the latter."
