Sampling audio at 48 kHz does not work with my Terratec Cinergy 600. Recording starts without trouble but the resulting stream is full of annoying crackles and is essentially unusable. 32 kHz sampling works mostly fine. However, according to the specs saa7134 is supposed to be able to sample at 32, 44.1 and 48 kHz. Interestingly, the Windows driver seems to support only 32 kHz, stereo, 16 bit sampling and its documentation claims it is the only format supported by the card. Besides, under Linux I get only silence when sampling in mono or 8 bits, so this particular format is the only I have got working. Is it possible that individual cards do not support the whole spectrum offered by the chip and why would manufacturers do that? Or is this more likely a Linux driver issue? I use version 0.2.7 but 20030605-snapshot did not help. The Linux driver does not support 44.1 kHz at all. Is there a particular reason for that? Finally, I experienced a lot of strange behavior with Line-In. Firstly, the card nearly drops the left channel of a stereo signal. The left channel is sampled so quietly compared to the right that it is practically lost. The same happens with both pci streaming and the audio pass-through but everything works if the audio source is plugged straight to the sound card. TV can be recorded in stereo without problem. This behavior occurs both under Linux and Windows, so I suspect it is a hardware fault, am I right? I have not noticed that any balance control had an effect. Secondly, the sampled audio stream has irritating spikes for a couple seconds in the beginning (even at 32 kHz rate) but only if the recording source is LINE1. There are considerably more spikes on the left channel - with near silence with them - could this be connected with the above? Besides, these spikes do not always occur. I use command sox -t ossdsp -r 32000 -c 2 -s -w /dev/dsp1 -t ossdsp /dev/dsp where dsp1 is the Cinergy card and dsp is my sound card. Thanks.
