2007-10-17Don't limit cx88 audio routing to blackbird boardsRicardo Cerqueira
From: Ricardo Cerqueira <v4l@cerqueira.org> All cx2388 boards need the line-in audio to be routed from an external ADC (refered to as "ADC mode" in the spec sheet), since the chip is uncapable of dealing with baseband audio directly. So... this patch enables normal mode when using the tuner (TV or Radio), and enables ADC mode with any other source. It'll probably only work with boards that have supported ADCs (such as the Wolfson wm9775) Signed-off-by: Ricardo Cerqueira <v4l@cerqueira.org>

From: Ricardo Cerqueira <v4l@cerqueira.org> Fix lack of audio on the MPEG-2 stream of wm8775 based blackbirds. The wm8775 module initializes the audio input at "route 2", which doesn't hold true for all boards. The HVR-1300, for example, uses route 1 for tuner audio, and route 2 for baseband. So we must route the audio to the proper input depending on what video input is being used. Signed-off-by: Ricardo Cerqueira <v4l@cerqueira.org> Signed-off-by: Michael Krufky <mkrufky@linuxtv.org>

2007-05-21cx88-blackbird: audio improvementsMichael Krufky
From: Jelle Foks <jelle@foks.8m.com> This patch should fix the 'muted audio' and 'raspy audio' problem for mpeg2 streams out of cx88-blackbird devices. Especially mythtv users would find that the audio would often sound bad (aliased, or 'raspy'), mainly related to channel changes, many (all?) other users would find that there was no audio at all in the mpeg data from the encoder chip, unless the audio was manually unmuted. The patch includes the following modifications: Don't actually start the mpeg2 encoder until the device is read from by the application. Wait until the audio is stable for at least 400ms before starting the mpeg encoder. Mute/Unmute the audio when starting/stopping the mpeg encoder. Stop the mpeg encoder when changing parameters and when changing tuner frequency. Add a variable 'mpeg_active' to struct cx8802_dev to allow tracking of whether or not the mpeg2 encoder is active.

From: Mauro Carvalho Chehab <mchehab@infradead.org> Currently, the only tuner-specific device that allows special configurations is tda9887. However, tea5767 also may require some special configurations (for example, to specify a different Xtal freq). This patch replaces TDA9887_SET_CONFIG by a more generic internal ioctl (TUNER_SET_CONFIG). The newer one allows specifying what tuner is appliable to a configuration set, and allows an arbitrary configuration struct. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-10-13cx88: Change (struct cx8802_dev)->drvlist to a list_head and fix bugsTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> It was a struct cx8802_driver for no apparent reason. Nothing uses a cx8802_driver in the cx8802_dev struct. The only field that was used was devlist, a list_head. The code in cx8802_remove() that removed any loaded sub-drivers was broken. It would delete the current list entry, but didn't use list_for_each_safe. It also called list_del() on the list _head_ inside the list_for_each loop? It would crash if it was run, which I don't think can ever happen. Since the cx8802 sub-drivers use the cx8802 driver, they have to be unloaded first. So there isn't any way for a sub-driver to still be loaded when cx8802_remove() is called... Except maybe with PCI hot-plug, if one removes the PCI card while the drivers are loaded? So I left some code in to handle that if it's actually possible. It will remove the sub-drivers from the device cx8802_remove() was called on, and only that device. If one has two DVB cards and unplugs one, there is no reason to unload the DVB drivers for both cards. I have no way to test this, but it can't be worse than what was there before. cx8802_get_driver() is passed a cx8802_dev pointer and looks for the requested driver on that device. It first loops over the cx8802 device list looking for the device it was passed, which is pointless. It doesn't need to find the device pointer in the list, as it already has the pointer. The list_head in the cx8802_driver struct, which joins all the _drivers_ attached to a device, was named devlist. Changed that to drvlist, since the devlist is used for a list of _devices_ in other cx8802 structs. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Reviewed-by: Michael Krufky <mkrufky@linuxtv.org>

Make the field conditional on VP3045 support. It was already conditional on DVB support, but it's only used if VP3045 support is on, so that makes for a better option to check.

But in these cases, it makes more sense to use CONFIG_VIDEO_SAA7134_DVB or CONFIG_VIDEO_CX88_DVB_MODULE depending on the driver. The reference in cx23885.h should just be removed, as the code there needs to be included if DVB is on or off. I do not think you can even compile the cx23885 driver without DVB. It's clearly just leftover from when the file was obvious copied from the cx88 driver (which is not mentioned in the copyright BTW). Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

2007-09-06cx88-alsa: Add mute controls, change control namesTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Add two mute controls. One mutes everything, the other just mutes the analog pass-through output. Rename the existing volume control. The controls are now: Playback Volume Playback Switch Capture Switch These names might seem odd, but I believe they are more correct. The previous "Capture Volume" control didn't actually effect the volume of the captured audio. Instead it controls the volume of the analog pass-thought output. It appears that pass-through controls like this are usually considered to be in the playback direction, not capture. For example, "CAPTURE feedback Playback Volume" is the name used for a control that appears to have the same effect in the ca0106 driver. We only have one volume control, so we can omit the "CAPTURE feedback" part. If someone where to add PCM playback support to the driver, then this would be the volume control.

2007-09-06cx88-alsa: Make volume control stereoTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Use the balance control to make the mono volume control stereo. Note that full range isn't supported. The balance control attenuates one channel by 0 to -63 dB, and the volume control provides additional attenuation to both channels by another 0 to -63 dB. So the channel with the most attenuation has a range of 0 to -126 dB, while the other channel only has a range of 0 to -63 dB. ALSA volume controls don't appear to support this concept. I just limited the range to 0 to -63 total. Once you get to -63 dB, you're already at silence, so additional attenuation is pretty much pointless anyway.
